The change can automatically update names for *.cc files that
are part of a backport.
contrib/ChangeLog:
* git-backport.py: Support renaming of .cc files.
It's very unlikely that somebody is going to backport a revision
that is > 14 months old to a release branch.
contrib/ChangeLog:
* git-backport.py: Simplify the script as pre-auto-ChangeLog era
is 14 months old.
I've just tested the script and I'm going to install the patch
to all active branches.
contrib/ChangeLog:
* git-backport.py: The script did 'git co HEAD~' when
there was no modified ChangeLog file in a successful
git cherry pick.
Run cherry-pick --continue without editor.
