Just for the record, \s in Perl doesn't mean SP; it means any whitespace
(including form feed and vertical tab, as well as CR, LF, TAB, and SP).
That's another one of the reasons why adding \s to our wildmat syntax
doesn't strike me as the best idea.  Does it match FF and VT too, if we
leave those in headers without converting them to spaces (and I don't see
why we couldn't do that)?
