This script is one of the sizeable ones that tempted people to copy
its "neibouring style" in their new code, but was littered with
styles incompatible with our style guide.
- use one tab, not four spaces, per indent level;
- long lines can be wrapped after '|', '&&', or '||' for
readability.
- structures like "if .. then .. else .. fi", "while .. do .. done"
are split into lines in such a way that does not require
unnecessary semicolon.
- case, esac and case-arms align at the same column.

This way we do not have to risk the list of tools going out of sync
between the implementation and the documentation.
In the same spirit as bf73fc2 (difftool: print list of valid tools
with '--tool-help', 2012-03-29), trim the list of merge backends in
the documentation. We do not want to have a complete list of valid
tools; we only want a list to help people guess what kind of things
the tools do to be specified there, and refer them to --tool-help
for a complete list.

Some merge tools cannot cope when $LOCAL, $BASE, or $REMOTE are missing.
$BASE can be missing when two branches independently add the same
filename.
Provide an empty file to make these tools happy.
When a delete/modify conflict occurs, $LOCAL and $REMOTE can also be
missing. We have special case code to handle such case so this change
may not affect that codepath, but try to be consistent and create an
empty file for them anyway.

Earlier code wanted to run merge_file and prompt_after_failed_merge
both of which wanted to read from the standard input of the entire
script inside a while loop, which read from a pipe, and in order to
do so, it redirected the original standard input to another file
descriptor. We no longer need to do so after the previous change.

Mergetool now treats its path arguments as a pathspec (like other git
subcommands), restricting action to the given files and directories.
Files matching the pathspec are filtered so mergetool only acts on
unmerged paths; previously it would assume each path argument was in an
unresolved state, and get confused when it couldn't check out their
other stages.
Running "git mergetool subdir" will prompt to resolve all conflicted
blobs under subdir.

When the index has conflicted submodules, mergetool used to mildly
clobber the module, renaming it to mymodule.BACKUP.nnnn, then failing to
copy it non-recursively.
Recognize submodules and offer a resolution instead:
Submodule merge conflict for 'Shared':
{local}: submodule commit ad9f12e3e6205381bf2163a793d1e596a9e211d0
{remote}: submodule commit f5893fb70ec5646efcd9aa643c5136753ac89253
Use (l)ocal or (r)emote, or (a)bort?
Selecting a commit will stage it, but not update the submodule (as git
does had there been no conflict). Type changes are also supported,
should the path be a submodule on one side, and a file, symlink,
directory, or deleted on the other.

Since bb0a484 (mergetool: Skip autoresolved paths, 2010-08-17),
mergetool uses different ways of figuring out the list of files with
merge conflicts depending on whether rerere is active. If rerere is
active, mergetool will use 'git rerere status' to list the files with
remaining conflicts. However, the output from that command does not
list conflicts of types that rerere does not handle, such as
modify/remove conflicts.
Another problem with solely relying on the output from 'git rerere
status' is that, for new conflicts that are not yet known to rerere,
the output from the command will list the files even after adding them
to the index. This means that if the conflicts in some files have been
resolved and 'git mergetool' is run again, it will ask the user
something like the following for each of those files.
file1: file does not need merging
Continue merging other unresolved paths (y/n) ?
Solve both of these problems by replacing the call to 'git rerere
status' with a call to the new 'git rerere remaining' that was
introduced in the previous commit.

mergetool used /dev/tty to switch back to receiving input from the user

When mergetool is run without path limiters it loops
over each entry in 'git ls-files -u'. This includes
autoresolved paths.
Teach mergetool to only merge files listed in 'rerere status'
when rerere is enabled.
There are some subtle but harmless changes in behavior.
We now call cd_to_toplevel when no paths are given.
We do this because 'rerere status' paths are always relative
to the root. This is beneficial for the non-rerere use as
well in that mergetool now runs against all unmerged files
regardless of the current directory.
This also slightly tweaks the output when run without paths
to be more readable.
The old output:
Merging the files: foo
bar
baz
The new output:
Merging:
foo
bar
baz

The mergetool--lib scriplet was tricky to use because it relied upon
the existance of several global shell variables. This removes more
global variables so that things are simpler for callers.
A side effect is that some variables are recomputed each time
run_merge_tool() is called, but the overhead for recomputing
them is justified by the simpler implementation.

Currently git mergetool is restricted to a set of commands defined
in the script. You can subvert the mergetool.<tool>.path to force
git mergetool to use a different command, but if you have a command
whose invocation syntax does not match one of the current tools then
you would have to write a wrapper script for it.
This patch adds two git config variable patterns which allow a more
flexible choice of merge tool.
If you run git mergetool with -t/--tool or the merge.tool config
variable set to an unrecognized tool then git mergetool will query the
mergetool.<tool>.cmd config variable. If this variable exists, then git
mergetool will treat the specified tool as a custom command and will use
a shell eval to run the command with the documented shell variables set.
mergetool.<tool>.trustExitCode can be used to indicate that the exit
code of the custom command can be used to determine the success of the
merge.

This commit adds a mechanism to provide absolute paths to the
external programs called by 'git mergetool'. A path can be
specified in the configuation variable mergetool.<tool>.path.
The configuration variable is similar to how we name branches

about a tool.
The mechanism is especially useful on Windows, where external
programs are unlikely to be in PATH.

A lot of shell scripts contained stuff starting with
while case "$#" in 0) break ;; esac
and similar. I consider breaking out of the condition instead of the
body od the loop ugly, and the implied "true" value of the
non-matching case is not really obvious to humans at first glance. It
happens not to be obvious to some BSD shells, either, but that's
because they are not POSIX-compliant. In most cases, this has been
replaced by a straight condition using "test". "case" has the
advantage of being faster than "test" on vintage shells where "test"
is not a builtin. Since none of them is likely to run the git
scripts, anyway, the added readability should be worth the change.
