[PATCH] cherry-pick: Bug fix 'cherry picked from' message.

["Shawn O. Pearce" <spearce@spearce.org>]

Somewhere along the line (in abd6970a) git-revert.sh learned to
omit the private object name from the new commit message *unless*
-x was supplied on the command line by the user.

The way this was implemented is really non-obvious in the original
script.  Setting replay=t (the default) means we don't include the
the private object name, while setting reply='' (the -x flag) means
we should include the private object name.  These two settings now
relate to the replay=1 and replay=0 cases in the C version, so we
need to negate replay to test it is 0.

I also noticed the C version was adding an extra LF in the -x case,
where the older git-revert.sh was not.
