I almost changed this to correspond to the lexer pattern ([a-z0-9][-\w]*) but
that isn't quite right either (it would reintroduce the '::' problem).  Another
option I considered was [^\[]+, but that has it's own problems.  In the end I
just made the minimal change, adding '-' to the acceptable characters.
