I don't speak rtl languages and don't know the support status for
them. But to me rtl on terminal is a terrible idea as it's assumed
everywhere that the terminal prints from left to right. Anyway let's
wait until a rtl translation comes to git, then we'll have somebody
knowledgable about the languages to talk about.

I was confused about what this means (why would it be faster to call
gettext() once inside print_ref_status() instead of once per caller
in the argument to print_ref_status()?) until I looked at the code.
I guess you mean something like

Mark strings like "[up to date]" passed to print_ref_status() for
translation with N_() instead of _() so they can remain untranslated
in porcelain mode.

Thanks.

Nit: "Compensate for the ...".

What would happen if 'width' became negative?  That can't happen
because none of the doublewidth characters are ASCII characters, so
the question is just academic, but maybe it's worth a note in the
comment to avoid slowing down people reading.

I'm not sure this is correct for right-to-left languages.  Something
to solve another day.

The rest looks good.
