Improve the regex Lisp syntax by allowing strings to specify

character compounds. I.e. the syntax "foo" is equivalent to the
cumbersome canonical form (compound #\f #\o #\o).

* regex.c (nfa_compile_regex, dv_compile_regex): Use chrp function
instead of typeof. Handle stringp case by forming a compound out of the
characters and recursing. Check for some bad objects in the regex
that would never come out of our regex parser but could occur
in a "hand crafted" syntax tree.
