When a patch inserts a block of lines, whose last lines are the
same as the existing lines that appear before the inserted block,
"git diff" can choose any place between these existing lines as the
boundary between the pre-context and the added lines (adjusting the
end of the inserted block as appropriate) to come up with variants
of the same patch, and some variants are easier to read than others.
We have been trying to improve the choice of this boundary, and Git
2.11 shipped with an experimental "compaction-heuristic". Since
then another attempt to improve the logic further resulted in a new
"indent-heuristic" logic. It is agreed that the latter gives better
result overall, and the former outlived its usefulness.
Retire "compaction", and keep "indent" as an experimental feature.
The latter hopefully will be turned on by default in a future
release, but that should be done as a separate step.

If a submodule was renamed at any point since it's inception then if you
were to try and grep on a commit prior to the submodule being moved, you
wouldn't be able to find a working directory for the submodule since the
path in the past is different from the current path.
This patch teaches grep to find the .git directory for a submodule in
the parents .git/modules/ directory in the event the path to the
submodule in the commit that is being searched differs from the state of
the currently checked out commit. If found, the child process that is
spawned to grep the submodule will chdir into its gitdir instead of a
working directory.
In order to override the explicit setting of submodule child process's
gitdir environment variable (which was introduced in '10f5c526')
`GIT_DIR_ENVIORMENT` needs to be pushed onto child process's env_array.
This allows the searching of history from a submodule's gitdir, rather
than from a working directory.

grep: enable recurse-submodules to work on <tree> objects
Teach grep to recursively search in submodules when provided with a
<tree> object. This allows grep to search a submodule based on the state
of the submodule that is present in a commit of the super project.
When grep is provided with a <tree> object, the name of the object is
prefixed to all output. In order to provide uniformity of output
between the parent and child processes the option `--parent-basename`
has been added so that the child can preface all of it's output with the
name of the parent's object instead of the name of the commit SHA1 of
the submodule. This changes output from the command
`git grep -e. -l --recurse-submodules HEAD` from:
HEAD:file
<commit sha1 of submodule>:sub/file
to:
HEAD:file
HEAD:sub/file

Allow grep to recognize submodules and recursively search for patterns in
each submodule. This is done by forking off a process to recursively
call grep on each submodule. The top level --super-prefix option is
used to pass a path to the submodule which can in turn be used to
prepend to output or in pathspec matching logic.
Recursion only occurs for submodules which have been initialized and
checked out by the parent project. If a submodule hasn't been
initialized and checked out it is simply skipped.
In order to support the existing multi-threading infrastructure in grep,
output from each child process is captured in a strbuf so that it can be
later printed to the console in an ordered fashion.
To limit the number of theads that are created, each child process has
half the number of threads as its parents (minimum of 1), otherwise we
potentailly have a fork-bomb.

When initializing a grep_source with type `GREP_SOURCE_SUBMODULE` the

used) or a SHA1 (the REV of the submodule to be grep'd). If the

`GREP_SOURCE_SHA1` case to handle the copying of the SHA1.

real_path: canonicalize directory separators in root parts
When an absolute path is resolved, resolution begins at the first path
component after the root part. The root part is just copied verbatim,
because it must not be inspected for symbolic links. For POSIX paths,
this is just the initial slash, but on Windows, the root part has the
forms c:\ or \\server\share. We do want to canonicalize the back-slashes
in the root part because these parts are compared to the result of
getcwd(), which does return a fully canonicalized path.
Factor out a helper that splits off the root part, and have it
canonicalize the copied part.
This change was prompted because t1504-ceiling-dirs.sh caught a breakage

mingw: fix colourization on Cygwin pseudo terminals
Git only colours the output and uses pagination if isatty() returns 1.
MSYS2 and Cygwin emulate pseudo terminals via named pipes, meaning that
isatty() returns 0.
f7f90e0f4f (mingw: make isatty() recognize MSYS2's pseudo terminals
(/dev/pty*), 2016-04-27) fixed this for MSYS2 terminals, but not for
Cygwin.
The named pipes that Cygwin and MSYS2 use are very similar. MSYS2 PTY pipes
are called 'msys-*-pty*' and Cygwin uses 'cygwin-*-pty*'. This commit
modifies the existing check to allow both MSYS2 and Cygwin PTY pipes to be
identified as TTYs.
Note that pagination is still broken when running Git for Windows from
within Cygwin, as MSYS2's less.exe is spawned (and does not like to
interact with Cygwin's PTY).

When determining whether a handle corresponds to a *real* Win32 Console
(as opposed to, say, a character device such as /dev/null), we use the
GetConsoleOutputBufferInfo() function as a tell-tale.
However, that does not work for *input* handles associated with a
console. Let's just use the GetConsoleMode() function for input handles,
and since it does not work on output handles fall back to the previous
method for those.
This patch prepares for using is_console() instead of my previous
