description:
If we're going xsrc hunting, lets's do it properly.   In particular
it is not "good" just because ../xsrc or /usr/xsrc exists, if the user said
-X /no/xsrc/here ...   Further, when we find it, remember it.

While here, also look in my favourite place: .../src/xsrc - src/x would be
better (or src/x11) but that's too hard given the cvs module name and src
tarball format.
