You are right about "we may be depending on what 2.1 has other than
-A".  Will apply as-is.

Thanks, both.

The primary reason I asked about '\[-A\]' was what will happen if
somebody uses 2.2.

Yes, it would be nice to be able to easily check >2.1. GNU expr seems to
handle this ok:

  $ expr 2.2 '>' 2.1
  1
  $ expr 2.0 '>' 2.1
  0

but POSIX seems to mention only integers and string comparison (though
if all are of the form "x.y", string comparison works). I have no idea
how portable this is.

Yeah, but it is the same thing -- we know 2.1 works, we do not know if
2.2 will break things for us ;-)

We'll worry about it when somebody with 2.2 complains.
