Subject: man pages for diff et al.
I finally got tired of not having man pages for diff and friends, so I
edited the appropriate sections of the texinfo manual into man format.
No user visable changes, I just want to keep things in sync to make sure
that integrating future versions of diffutils will continue to be relatively
painless.
for diff3 and sdiff access them through the .PATH: construct. This
allows all the source to be contained in the diff directory, and
should make it a little bit easier to upgrade to newer versions of diff.
