Saying "a lot of work" would be an understatement!

I would normally not have touched it as it was not part of my core
mission,
but "__xconfigfile__" was already used in other man pages such as
libXxf86vm which draws the text from util-macros MAN_SUBSTS.

Even if the server would change the name, it would remain intact
everywhere else. In the server man pages I would've had to deal with
conflicting substitutions.

Anyway I slice it, something would have to change on the next fork, 
but I won't be around :-)

Thanks for the review, I fixed the typo multiple instances.
