The git-rev-parse manpage talks about the :$n:path notation (buried deep in
a list of other syntax) but it just says $n is a "stage number" -- someone
who is not familiar with the internals of git's merge implementation is
never going to be able to figure out that "1", "2", and "3" means.

This hides the backslash at the end of line from AsciiDoc
toolchain by introducing a trailing whitespace on one line in an
illustration in git-rev-parse.txt.

This uses "git-apply --whitespace=strip" to fix whitespace errors that have
crept in to our source files over time. There are a few files that need
to have trailing whitespaces (most notably, test vectors). The results
still passes the test, and build result in Documentation/ area is unchanged.

setup_gdg is used as abbreviation for setup_git_directory_gently.
The work tree can be specified using the environment variable
GIT_WORK_TREE and the config option core.worktree (the environment
variable has precendence over the config option). Additionally
there is a command line option --work-tree which sets the
environment variable.
setup_gdg does the following now:
GIT_DIR unspecified
repository in .git directory
parent directory of the .git directory is used as work tree,
GIT_WORK_TREE is ignored
GIT_DIR unspecified
repository in cwd
GIT_DIR is set to cwd
see the cases with GIT_DIR specified what happens next and
also see the note below
GIT_DIR specified
GIT_WORK_TREE/core.worktree unspecified
cwd is used as work tree
GIT_DIR specified
GIT_WORK_TREE/core.worktree specified
the specified work tree is used
Note on the case where GIT_DIR is unspecified and repository is in cwd:
GIT_WORK_TREE is used but is_inside_git_dir is always true.
I did it this way because setup_gdg might be called multiple
times (e.g. when doing alias expansion) and in successive calls
setup_gdg should do the same thing every time.
Meaning of is_bare/is_inside_work_tree/is_inside_git_dir:
(1) is_bare_repository
A repository is bare if core.bare is true or core.bare is
unspecified and the name suggests it is bare (directory not
named .git). The bare option disables a few protective
checks which are useful with a working tree. Currently
this changes if a repository is bare:
updates of HEAD are allowed
git gc packs the refs
the reflog is disabled by default
(2) is_inside_work_tree
True if the cwd is inside the associated working tree (if there
is one), false otherwise.
(3) is_inside_git_dir
True if the cwd is inside the git directory, false otherwise.
Before this patch is_inside_git_dir was always true for bare
repositories.
When setup_gdg finds a repository git_config(git_default_config) is
always called. This ensure that is_bare_repository makes use of
core.bare and does not guess even though core.bare is specified.
inside_work_tree and inside_git_dir are set if setup_gdg finds a
repository. The is_inside_work_tree and is_inside_git_dir functions
will die if they are called before a successful call to setup_gdg.

Please see http://bugs.debian.org/404795:
In git-rev-parse(1), there is an example commit tree, which is used twice.
The explanation for this tree is very clear: B and C are commit *parents* to
A.
However, when the tree is reused as an example in the SPECIFYING RANGES, the
manpage author screws up and uses A as a commit *parent* to B and C! I.e.,
he inverts the tree.
And the fact that for this example you need to read the tree backwards is
not explained anywhere (and it would be confusing even if it was).

To name a commit, you can now say
$ git rev-parse ':/Initial revision of "git"'
and it will return the hash of the youngest commit whose
commit message (the oneline) begins with the given prefix.
For future extension, a leading exclamation mark is treated
specially: if you want to match a commit message starting with
a '!', just repeat the exclamation mark. So, to match a commit
which starts with '!Hello World', use
$ git show ':/!!Hello World'

This is a shorthand for "<rev> --not <rev>^@", i.e. "include
this commit but exclude any of its parents".
When a new file $F is introduced by revision $R, this notation
can be used to find a copy-and-paste from existing file in the
parents of that revision without annotating the ancestry of the
lines that were copied from:
git pickaxe -f -C $R^! -- $F

Nobody should create ambiguous refs (i.e. have tag "foobar" and branch

Its ambiguous to parse "master@2006-05-17 18:30:foo" when foo is
meant as a file name and ":30" is meant as 30 minutes past 6 pm.
Therefore all date specifications in a sha1 expression must now
appear within brackets and the ':' splitter used for the path name
in a sha1 expression ignores ':' appearing within brackets.

Extended sha1 expressions may now include date specifications
which indicate a point in time within the local repository's
history. If the ref indicated to the left of '@' has a log in
$GIT_DIR/logs/<ref> then the value of the ref at the time indicated
by the specification is obtained from the ref's log.

When --show-prefix is useful, sometimes it is easier to cd up to
the toplevel of the tree. This is equivalent to:
git rev-parse --show-prefix | sed -e 's|[^/][^/]*|..|g'
