Fixed a regular expression bug.  
Repeat by:  
string: "caaad"
pattern: c[a]*d

Fix:  in the procedure 'match_one_or_more' in the file e_regex.c
replace the commented out line of code with the one above it.

---------------------------------------------------------------------------

	/* If the recursion didn't succeed, then does the termination */
	/* condition hold at this point?  If so, this is the maximal match */

		if (!(more_node -> matched)) {
                        if (next_pat == Nil) {
                                set_match_bounds(more_node,start,esave);
				break;
                        }        
                        match_at_position(next_pat,esave + 1,Nil);
/*			match_at_position(next_pat,curpos,Nil); */
			if (next_pat -> matched) {
				set_match_bounds(more_node,start,esave);
			}

		}
