Here's a quick writeup in a hurry of what was listed so far.
Thanks. I proposed it to rms, with minor changes.
Autoconf would like to move to shell functions in the not too distant
I agree that shell functions are ok. I don't think the wording
prohibits that.
virtually all systems have a posixy shell
Yes, and that's fine for scripts which can search for it and exec
themselves to use it, but it doesn't help with Makefile rules -- or am I
missing something? Those should still be least-common-denominator
vanilla sh, I think.
Thanks,
k
