Hmm, maybe this one is overkill.  $((...)) is POSIX, I temporarily
forgot (thanks Benoît!).

I'm unsure whether git targets non-POSIX Bourne shells like Solaris
/bin/sh.  That would however mean replacing stuff like $(cmd) with
`cmd` as well, and from grepping the source it looks like you'd rather
avoid that.

Cheers,
