Traditionally, a cleanly resolved merge was committed by "git merge" using
the auto-generated merge commit log message without invoking the editor.
After 5 years of use in the field, it turns out that people perform too
many unjustified merges of the upstream history into their topic branches.
These merges are not just useless, but they are often not explained well,
and making the end result unreadable when it gets time for merging their
history back to their upstream.
Earlier we added the "--edit" option to the command, so that people can
edit the log message to explain and justify their merge commits. Let's
take it one step further and spawn the editor by default when we are in an
interactive session (i.e. the standard input and the standard output are
pointing at the same tty device).
There may be existing scripts that leave the standard input and the
standard output of the "git merge" connected to whatever environment the
scripts were started, and such invocation might trigger the above
"interactive session" heuristics. GIT_MERGE_AUTOEDIT environment variable
can be set to "no" at the beginning of such scripts to use the historical
behaviour while the script runs.
Note that this backward compatibility is meant only for scripts, and we
deliberately do *not* support "merge.edit = yes/no/auto" configuration
option to allow people to keep the historical behaviour.

Implemented internally instead of as "git merge --no-commit && git commit"
so that "merge --edit" is otherwise consistent (hooks, etc) with "merge".
Note: the edit message does not include the status information that one
gets with "commit --status" and it is cleaned up after editing like one
gets with "commit --cleanup=default". A later patch could add the status
information if desired.
Note: previously we were not calling stripspace() after running the
prepare-commit-msg hook. Now we are, stripping comments and
leading/trailing whitespace lines if --edit is given, otherwise only
stripping leading/trailing whitespace lines if not given --edit.

The user can enable or disable it explicitly with the new
--progress, but it defaults to checking isatty(2).
This works only with merge-recursive and subtree. In theory
we could pass a progress flag to other strategies, but none
of them support progress at this point, so let's wait until
they grow such a feature before worrying about propagating
it.

The documentation was quite inconsistent when spelling 'git cmd' if it
only refers to the program, not to some specific invocation syntax:
both 'git-cmd' and 'git cmd' spellings exist.
The current trend goes towards dashless forms, and there is precedent
in 647ac70 (git-svn.txt: stop using dash-form of commands.,
2009-07-07) to actively eliminate the dashed variants.
Replace 'git-cmd' with 'git cmd' throughout, except where git-shell,
git-cvsserver, git-upload-pack, git-receive-pack, and
git-upload-archive are concerned, because those really live in the
$PATH.
For convenience in scripts and aliases, add the option
--ff-only to only allow fast-forwards (and up-to-date,
despite the name).
Disallow combining --ff-only and --no-ff, since they
flatly contradict each other.
Allow all other options to be combined with --ff-only
(i.e. do not add any code to handle them specially),
including the following options:
* --strategy (one or more): As long as the chosen merge
strategy results in up-to-date or fast-forward, the
command will succeed.
* --squash: I cannot imagine why anyone would want to
squash commits only if fast-forward is possible, but I
also see no reason why it should not be allowed.
* --message: The message will always be ignored, but I see
no need to explicitly disallow providing a redundant message.
Acknowledgements: I did look at Yuval Kogman's earlier
patch (107768 in gmane), mainly as shortcut to find my
way in the code, but I did not copy anything directly.

The OPTIONS section of a documentation file contains a list
of the options a git command accepts.
Currently there are several variants to describe the case that
different options (almost) do the same in the OPTIONS section.
Some are:
-f, --foo::
-f|--foo::
-f | --foo::
But AsciiDoc has the special form:
-f::
--foo::
This patch applies this form to the documentation of the whole git suite,
and removes useless em-dash prevention, so \--foo becomes --foo.

This option has the same effect as '--(no-)summary' (i.e. whether to

These options can be used to override --no-commit and --squash, which is
needed since --no-commit and --squash now can be specified as default merge
options in $GIT_DIR/config.
The change also introduces slightly different behavior for --no-commit:
when specified, it explicitly overrides --squash. Earlier,
'git merge --squash --no-commit' would result in a squashed merge (i.e. no
$GIT_DIR/MERGE_HEAD was created) but with this patch the command will
behave as if --squash hadn't been specified.

Some people tend to do many little commits on a topic branch,
recording all the trials and errors, and when the topic is
reasonably cooked well, would want to record the net effect of
the series as one commit on top of the mainline, removing the
cruft from the history. The topic is then abandoned or forked
off again from that point at the mainline.
The barebone porcelainish that comes with core git tools does
not officially support such operation, but you can fake it by
using "git pull --no-merge" when such a topic branch is not a
strict superset of the mainline, like this:
git checkout mainline
git pull --no-commit . that-topic-branch
: fix conflicts if any
rm -f .git/MERGE_HEAD
git commit -a -m 'consolidated commit log message'
git branch -f that-topic-branch ;# now fully merged
This however does not work when the topic branch is a fast
forward of the mainline, because normal "git pull" will never
create a merge commit in such a case, and there is nothing
special --no-commit could do to begin with.
This patch introduces a new option, --squash, to support such a
workflow officially in both fast-forward case and true merge
case. The user-level operation would be the same in both cases:
git checkout mainline
git pull --squash . that-topic-branch
: fix conflicts if any -- naturally, there would be
: no conflict if fast forward.
git commit -a -m 'consolidated commit log message'
git branch -f that-topic-branch ;# now fully merged
When the current branch is already up-to-date with respect to
the other branch, there truly is nothing to do, so the new
option does not have any effect.
This was brought up in #git IRC channel recently.
