This does replace Str_Match with a better routine, which handles negated
intervals, and \\ in intervals.

Accordingly, var.c no longer needs to copy the :Marg to replace \: with :

We don't use fnmatch(3) because of various optimizations which are harder
to achieve in a generic setting.

Also add regression suite for the Str_Match function.
