This commit refactors git stash show to make use of the assert_stash_like function.
git show now dies if the presented argument is non-stash-like.
Previous behaviour was to tolerate commits that were not even stash-like.
Previously, git stash show would accept stash-like arguments, but
only if there was a stash on the stack.
Now, git stash accepts stash-like arguments always and only fails
if no stash-like argument is specified and there is no stash stack.

This patch teaches git stash branch to tolerate stash-like arguments.
In particular, a stash is only required if an argument isn't specified
and the stash is only dropped if a stash entry reference was
specified or implied.
The implementation has been simplified by taking advantage of
assert_stash_like() and the variables established by
parse_flags_and_rev().

git stash pop is abstracted into its own implementation function - pop_stash.
The behaviour is changed so that git stash pop fails early if the
the specified stash reference does not exist or does not refer to
an extant entry in the reflog of the reference stash.
This fixes the case where the apply succeeds, but the drop fails.
Previously this caused caused git stash pop to exit with a non-zero exit code
and a dirty tree.
Now, git stash pop fails with a non-zero exit code, but the working
tree is not modified.

Previously, git stash drop would fail noisily while executing git reflog
delete if the specified revision was not a stash reference.
Now, git stash drop fails with an error message which more precisely
indicates the reason for failure.
Furthermore, git stash drop will now fail with a non-zero status code
if stash@{n} specifies a stash log entry that does not actually exist.
This change in behaviour is achieved by delegating argument parsing
to the common parse_flags_and_rev() function (via a call to
assert_stash_ref).

Introduce parse_flags_and_revs. This function requires that
there is at most one stash-like revision parameter and
zero or more flags.
It knows how to parse -q,--quiet and --index flags, but leaves
other flags parsed.
Specified revisions are checked to see that they are at
least stash-like (meaning: they look like something created
by git stash save or git stash create).
If this is so, then IS_STASH_LIKE is initialized to a non-empty value.
If the specified revision also looks like a stash log entry reference,
then IS_STASH_REF is initialized to a non-empty value.
References of the form ref@{spec} are required to precisely identify
an individual commit.
If no reference is specified, stash@{0} is assumed.
Once the specified reference is validated to be at least stash_like
an ensemble of derived variables, (w_commit, w_tree, b_commit, etc)
is initialized with a single call to git rev-parse.
Repeated calls to parse_flags_and_rev() avoid repeated calls
to git rev-parse if the specified arguments have already been
parsed.
Subsequent patches in the series modify the existing
git stash subcommands to make use of these functions
as appropriate.
An ensemble of supporting functions that make use of the state
established by parse_flags_and_rev(). These are described below:
The ancillary functions are:
is_stash_like(): which can be used to test
whether a specified commit looks like a commit created with
git stash save or git stash create.
assert_stash_like(): which can be used by
commands that misbehave unless their arguments stash-like.
is_stash_ref(): which checks whether an argument
is valid stash reference(e.g. is of the form
['refs/']stash['@{'something'}])
assert_stash_ref(): which can be used by commands
that misbehave unless their arguments are both stash-like and
refer to valid stash entries.

The use of git add -u in create_stash isn't always complete. In
particular, if a file has been removed from the index but changed in the
work tree it will not be added to the stash's saved work tree tree
object. When stash then resets the work tree to match HEAD, any changes
will be lost.
To be complete, any work tree file which differs from HEAD needs to be
saved, regardless of whether it still appears in the index or not.
This is achieved with a combination of a diff against HEAD and a call to
update-index with an explicit list of paths that have changed.

Because log.decorate now shows decorations for --pretty=oneline,
we must explicitly turn it off when scripting. Otherwise,

The 'git stash pop' option parsing used to remove the first argument
in --index mode. At the time this was implemented, this first
argument was always --index. However, since the invention of the -q
option in fcdd0e9 (stash: teach quiet option, 2009-06-17) you can
cause an internal invocation of
git stash drop --index
by running
git stash pop -q --index
which then of course fails because drop doesn't know --index.
To handle this, instead let 'git stash apply' decide what the future
argument to 'drop' should be.
Warning: this means that 'git stash apply' must parse all options that
'drop' can take, and deal with them in the same way. This is
currently true for its only option -q.

With the earlier DWIM patches, certain combination of options defaulted
to the "save" command correctly while certain equally valid combination
did not. For example, "git stash -k" were Ok but "git stash -q -k" did
not work.
This makes the logic of defaulting to "save" much simpler. If there are no
non-flag arguments, it is clear that there is no command word, and we
default to "save" subcommand. This rule prevents "git stash -q apply"
from quietly creating a stash with "apply" as the message.
This also teaches "git stash save" to reject an unknown option. This is
to keep a mistyped "git stash save --quite" from creating a stash with a
message "--quite", and this safety is more important with the new logic
to default to "save" with any option-looking argument without an explicit
comand word.

This adds a hunk-based mode to git-stash. You can select hunks from
the difference between HEAD and worktree, and git-stash will build a
stash that reflects these changes. The index state of the stash is
the same as your current index, and we also let --patch imply
--keep-index.
Note that because the selected hunks are rolled back from the worktree
but not the index, the resulting state may appear somewhat confusing
if you had also staged these changes. This is not entirely
satisfactory, but due to the way stashes are applied, other solutions
would require a change to the stash format.

The change makes sure a stash (given or default) exists before
checking if the working tree is dirty.
If the default stash is requested, the old message was scary and
included a 'fatal' error from rev-parse:
fatal: Needed a single revision
: no valid stashed state found
It is replaced with a friendlier 'Nothing to apply' error, similar to
'git stash branch'.
If a specific stash is specified, the 'Needed a single revision' errors
from rev-parse are suppressed.

'git stash pop' supports the '--index' option since its initial
implementation (bd56ff54, git-stash: add new 'pop' subcommand,
2008-02-22), but its documentation does not mention it explicitly.
Moreover, both the usage shown by 'git stash -h' and the synopsis
section in the man page imply that 'git stash pop' does not have an
'--index' option.
First, this patch corrects the usage and the synopsis section.
Second, the patch moves the description of the '--index' option to the
'git stash pop' section in the documentation, and refers to it from
the 'git stash apply' section. This way it follows the intentions of
commit d1836637 (Documentation: teach stash/pop workflow instead of
stash/apply, 2009-05-28), as all 'git stash pop'-related documentation
will be in one place without references to 'git stash apply'.

The referenced commit tried to fix a flaw in stash's handling of a user
supplied invalid ref. i.e. 'git stash apply fake_ref@{0}' should fail
instead of applying stash@{0}. But, it did so in a naive way by avoiding the
use of the --default option of rev-parse, and instead manually supplied the
default revision if the user supplied an empty command line. This prevented
a common usage scenario of supplying flags on the stash command line (i.e.
non-empty command line) which would be parsed by lower level git commands,
without supplying a specific revision. This should fall back to the default
revision, but now it causes an error. e.g. 'git stash show -p'
The correct fix is to use the --verify option of rev-parse, which fails
properly if an invalid ref is supplied, and still allows falling back to a
default ref when one is not supplied.
Convert stash-drop to use --verify while we're at it, since specifying
multiple revisions for any of these commands is also an error and --verify
makes it so.

apply_stash() and show_stash() each call rev-parse with
'--default refs/stash' as an argument. This option causes rev-parse to
operate on refs/stash if it is not able to successfully operate on any
element of the command line. This includes failure to supply a "valid"
revision. This has the effect of causing 'stash apply' and 'stash show'
to operate as if stash@{0} had been supplied when an invalid revision is
supplied.
e.g. 'git stash apply stash@{1}' would fall back to
'git stash apply stash@{0}'
This patch modifies these two functions so that they avoid using the
--default option of rev-parse.

"git stash -h" showed some incomplete and ugly usage information.
For example, the useful "--keep-index" option for "save" or the "--index"
option for "apply" were not shown. Also in the documentation synopsis they
were not shown, so that there is no incentive to scroll down and even see
that such options exist.
This patch improves the git-stash synopsis in the documentation by
mentioning that further options to the stash commands and then copies
this synopsis to the usage information string of git-stash.sh.
For the latter, the dashless git command string has to be inserted on the
second and the following usage lines. The code of this is taken from
git-sh-setup so that all lines will show the command string.
Note that the "create" command is not advertised at all now, because

'git stash save' saves local modifications to a new stash, and runs 'git
reset --hard' to revert them to a clean index and work tree. When the
'--keep-index' option is specified, after that 'git reset --hard' the
previous contents of the index is restored and the work tree is updated
to match the index. This option is useful if the user wants to commit
only parts of his local modifications, but wants to test those parts
before committing.
