[PATCH] Add --no-commit to git-merge/git-pull.
From: Junio C Hamano <hidden>

With --no-commit flag, git-pull will perform the merge but pretends as
if the merge needed a hand resolve even if automerge cleanly resolves,
to give the user a chance to add further changes and edit the commit
message.

This turns out to be useful while maintaining the maint branch
for 0.99.9[a-z] lettered maintenance releases. The plan is for
the contents of that branch to match always the tip of the
master branch during 0.99.9 timeframe, and every time a merge
is done from master into maint, only GIT_VERSION in the
Makefile is bumped up. 0.99.8 maintenance branch was done by
pulling from a private branch "fixes", immediately followed by
a separate commit to bump that definition up, but with this, I
could instead do this:
$ git checkout master
$ git am -3 -s ./++patches-from-the-list.mbox
... work work work in master ...
$ git checkout maint
$ git pull --no-commit . master
... update the version in Makefile and debian/changelog ...
$ git commit -a -m 'GIT 0.99.9b'
