Here's what's in 1003.2 (Draft 10). This is more than just
"proposed", it is very close to an approved standard. (There
certainly will be very few changes to this list.) Note that 1003.2 is
targeted to shell scripts, NOT to interactive users, so no more (pg,
less or whatever), vi, or such.

I wasn't in this particular group, so I don't know if perl was
discussed, and I don't know perl. However, if perl is just a "nicer"
way to do things than can also be done with sed and awk, I'm sure that
the reaction of the group would be that it is less widely used than
sed and awk, and provides no additional functionality. Just being
easier to use is not NECESSARILY a telling argument.

Existing practice is a criterium. HOW widely used is also. Also,
there should in general not be many ways to do the same thing.
