Justin Viiret 9a7b912a5d Rework parser rejection for POSIX collating elems
Implement rejection of POSIX collating elements ("[.ch.]" and "[=ch=]"
entirely in the Ragel parser, using the same approach both inside and
ouside character classes.

Fix buggy rejection of [^.ch.], which we should accept as a character
class.
