Summary: Regexps differ from Ex to Csh


The * is in Ex and friends is different from that in Csh.
xxxx*  in csh will match any pattern starting with four x's,
while in Ex it will match a string of at least 3 x's -
xxx and then (x*) == zero or more x's.

So for re_comp you need xxxx.*  which is 4 x's, and zero or more .'s
and . being a wild match which will match any single character.
