There were 3 mail messages this am pointing out the regular expression
was not anchored and the correct expression to pass to re_comp should

Ah the joys of terminal brain fade when you've been hard at it for

about pattern matching in the context of globbing instead of regular
expression matching. Thanks to all, and sorry to have wasted the net
bandwidth on something that should have been so obvious.
