patch to diff manpage - clarify "-x"

[Tomas Pospisek]

Please apply. For a discussion of the problem see:

        http://bugs.debian.org/166020

In short it is not clear from the manpage that exclusion of files and for
that matter patternmatching will only apply to _directories_.

Please contact me directly if you follow up.
