My idea is that AS is related to the shell, in anyway.  But I agree
with your concern.  But it's a valid point.  We could have m4_escape,
indeed, m4_dirname as presented by Derek, and import AC_INDIR_IF into
sh.m4, and have AS_DIRNAME and AS_ESCAPE polymorph depending whether
the computation can be done at m4 time or sh.

Any patch would be accepted for m4_escape :)
