Problem with regex using mx flags

[Dan Kohn]

Could you please take a look at this regex (line 52) that's just
killing me. (It's at <http://rafb.net/paste/results/l4U66N90.html> or
below). When I split it up (lines 44-49) it works fine. There must be
something obvious but I can't see it.

Sorry, that was silly. I was using m.match when I needed s.scan.
