Even Solaris /usr/xpg4/bin/sh has it. Their /bin/sh does not, but that is not a surprise: that shell is useless and already unsupported by git.

I don't know about other obscure platforms (wasn't there some guy running git on antique SCO machines or something?).

I think it is nice to shoot for "more portable" in general, and I don't particularly care one way or the other about this feature. But I think we are somewhat hampered by having no clue what the supported set of platforms is. I'm pretty sure we support at least:

  - various recent Linux distributions
  - FreeBSD 6.x (maybe as far back as 4.x)
  - OS X
  - NetBSD and OpenBSD, but no idea which versions
  - Solaris >= 2.8
  - AIX 5.3

and I suspect most of those have somebody building them regularly enough that breakages are caught. I have no idea what people are using beyond that, and how quickly they might catch a portability breakage.
