Subject: mdocml: Support the alternative syntax \C'uXXXX' for Unicode characters.

Log Message:
-----------
Support the alternative syntax \C'uXXXX' for Unicode characters.
It is already documented in the Heirloom troff manual,
and groff handles it as well.

Bug reported by Bjarni Ingi Gislason <bjarniig at rhi dot hi dot is>
on <bug-groff at gnu dot org>.  Well, admittedly, that bug was reported 
against groff, but mandoc was even more broken than groff with respect
to this syntax...
