-/*
-**  Do shell-style pattern matching for ?, \, [], and * characters.
-**  It is 8bit clean.
-**
-**  Written by Rich $alz, mirror!rs, Wed Nov 26 19:03:17 EST 1986.
-**  Rich $alz is now <rsalz@bbn.com>.
-**
-**  Modified by Wayne Davison to special-case '/' matching, to make '**'
-**  work differently than '*', and to fix the character-class code.
