Rebase pain on (the) pot

Do we have a merge driver or something for the l10n files?

I'm trying to rebase an older branch on top of origin/next. My topic
branch has changes to git.pot (the old glossary command idea), and
rebasing produces a lot of conflicts due to simple line number changes
in the comments. (The de.po in the next commit to be rebased won't fair
any better, probably.)
