I'm not so sure. I think a lot of people who did --match '\.html$' would
be miffed when they discover that the match fails on
"index.html?foo=bar". It depends somewhat on the site, but I think in
general :s-p: will be less surprising than :url:.

BTW, I'm starting to think "-" was a poor choice... it'd be nice to
reserve that for possible use in component names. Maybe :s..p: is the
best way to go after all.

I'm not crazy about that. It would save us the consumption of new
short-options, but...

I'm not sure I can identify what my objection is; obviously it'd break
any previous scripts that happen to match that pattern, but that has
gotta be pretty frikkin' rare.
