Wouldn't it be better to have the CVS code look like the GNU diff
code?  GNU diff already has the behavior that you desire.

The changes that you're proposing to context.c etc. implement the
"\ No newline..." behavior in using a different method than diffutils,
but I don't see the advantage of the way that you're proposing.

At some point in this millennium I'd like to have a diffutils library
that CVS can use.  In the meantime it'd be nicer to keep the two
codebases close if possible.
