1) Basic hex doesn't seem to work with regards to matching for certain hex
numbers.  For example do a data.data matches "\x29" or frame matches "\x28". 
The _expression_ immediately turns red. 

2) Furthermore the regex doesn't seem to work even when you use hex digits that
don't turn red.  Try to match a packet that has for example "\x4c......\x30"
(six anything bytes between 4c and 30) and it fails to match.

Tried the stable 1.10.7 and now the dev version both seem to have the problem.
