Fix regexp character classes with \uNNNN and \xNN code points

Browse Source 
Currently, if a regexp contains a character class and that
character class contains a hex-specified code point -- either
\uNNNN or \xNN --, then the character 'u' or 'x' is added to the
character class as well. This patch fixes the error and also adds
a regression test covering the issue.

Fixes #962
