Yes but no ;-). I've said this a few times on the list in the
past, but I'll repeat it again for new people.
We reject something whose portability in question by saying
"It's not _even in_ POSIX". We on the other hand try to refrain
from saying "POSIX says you are supposed to have it, so screw
people that are not fully POSIX".
Yes, I suppose. At the same time, git already implicitly requires more
than, say, a Bourne shell. Functions, $( ) command substitution, ${}
parameter expansion, $(( )) arithmetic expansion, etc. These are all
standard in a POSIX shell, but may or may not exist in other shell
variants.
