[PATCH libX11] Compose.man: fix escaped hexadecimal char description

RB>     ESCAPED_CHAR  ::= ('\\' | '\"' | OCTAL | HEX )
RB>     HEX           ::= '\' (x|X) HEX_CHAR [HEX_CHAR]]
RB>     HEX_CHAR      ::= (0|1|2|3|4|5|6|7|8|9|A|B|C|D|E|F|a|b|c|d|e|f)

Given that the original code was written for eight-bit encodings, I
suppose that is not surprising that the grammar is only cabable of
octal and hex octets.

I presume a different parser must be used for the XLC_LOCALE files,
as those have longer hex escapes (also using \x).

Should we fix the doc or update the parser to handle larger hex?

And on that front, should we add a \u escape to insert the utf-8 for
a given code point?
