[PATCH 0/5] branch: --sort improvements

This started out as a reading of ref-filter.c where I wondered why we needed this i18n lego. I'm not sure whether in Chinese what Matthew DeVore said in [1] is true, but in any case it seems better to leave that to the translators, re-using the string is a relatively small gain.

So I think that change was really just "ASCII sort is easier than checking a flag in a sort callback", fair enough. But I thought I'd try to see how hard that patch would be. Turned out it's rather easy & I think results in better code, 4/5 gets us to that point.

But 5/5 I think makes this more generally interesting. In all locales (including LC_ALL=C) we list the "HEAD detached" entry last in "git branch -l" output if you're doing a reverse sort. I don't think this makes any sense, it's a notice, not a refname to be sorted. Using the new sorting function for treating detached HEAD specially makes this trivial to fix.
