Junio C Hamano 7791ecbc62 revert/cherry-pick: work on merge commits as well
Usually you cannot revert a merge because you do not know which
side of the merge should be considered the mainline (iow, what
change to reverse).

With this patch, cherry-pick and revert learn -m (--mainline)
option that lets you specify the parent number (starting from 1)
of the mainline, so that you can:

	git revert -m 1 $merge

to reverse the changes introduced by the $merge commit relative
to its first parent, and:

	git cherry-pick -m 2 $merge

to replay the changes introduced by the $merge commit relative
to its second parent.

git-revert(1)
=============
NAME
----
git-revert - Revert an existing commit
SYNOPSIS
--------
'git-revert' [--edit | --no-edit] [-n] [-m parent-number] <commit>
DESCRIPTION
-----------
Given one existing commit, revert the change the patch introduces, and record a
new commit that records it. This requires your working tree to be clean (no
modifications from the HEAD commit).
OPTIONS
-------
<commit>::
Commit to revert.
For a more complete list of ways to spell commit names, see
"SPECIFYING REVISIONS" section in gitlink:git-rev-parse[1].
-e|--edit::
With this option, `git-revert` will let you edit the commit
message prior committing the revert. This is the default if
you run the command from a terminal.
-m parent-number|--mainline parent-number::
Usually you cannot revert a merge because you do not know which
side of the merge should be considered the mainline. This
option specifies the parent number (starting from 1) of
the mainline and allows revert to reverse the change
relative to the specified parent.
--no-edit::
With this option, `git-revert` will not start the commit
message editor.
-n|--no-commit::
Usually the command automatically creates a commit with
a commit log message stating which commit was reverted.
This flag applies the change necessary to revert the
named commit to your working tree, but does not make the
commit. In addition, when this option is used, your
working tree does not have to match the HEAD commit.
The revert is done against the beginning state of your
working tree.
+
This is useful when reverting more than one commits'
effect to your working tree in a row.
