Best I've seen in a bunch of testing:
rawbody   __LW_URI_CR1 /href=\"[^"]*\r[^\n]/is
full      __LW_URI_CR2 /href=\"[^"]*\r[^\n]/is
meta      LW_URI_CR  __LW_URI_CR1 || __LW_URI_CR2
score     LW_URI_CR  2
describe  LW_URI_CR  unescaped cr in uri
#hist     LW_URI_CR  Loren Wilton
#counts   LW_URI_CR  49s/0h of 292007 corpus (122219s/169788h RM) 04/27/05

Doesn't catch all of them, for reasons I haven't yet figured out, but
catches some, and no FPs here.
