syntaxes: colorize hex more strictly by using character class [:xdigit:]
...
In UTF-8 locales, the ranges A-F and a-f include several accented
characters beyond "ABCDEF" and "abcdef", such as the Croat č and ć.
This fixes https://savannah.gnu.org/bugs/?61487 .
Bug existed since the beginning of each of the syntaxes,
for the C syntax since version 1.3.6, commit 159bdfdc

syntax: po: highlight embedded control codes that shouldn't be there
...
For some reason the Romanian PO file contains a literal ^Q in one
of its translated messages -- currently at line 1984. This stray
^Q causes 'file' to classify po/ro.po as data.
Make such mistaken control codes easier to spot when using nano.

The different color will make the name stand out, as it should, instead
of looking the same as all the regex strings.
