Doesn't seem to do so, with my strenuous test of typing sh then trying
echo $UID.  The true Bourne shell doesn't have that (which messed
me up once when forgetting that and working on an AIX box.  I think
that's when I discovered that UID is a bash-ism and not a sh-ism. 

Note that that is the only test I did--it might be that everything else
is perfect. 

IIRC, back when that happened (writing something portable and needing to
test syntax), I got the best results with dash.

Angel: I knew this was gonna happen. 
Buffy: What? What do you think is happening? 
Angel: You're 16 years old, I'm 241. 
Buffy: I've done the math. 
Angel: You don't know what you're doing. You don't know what you 
want. 
Buffy: Oh, no. I think I do. I want out of this conversation.
