Damn, hadn't clued into the -u :(  unified diffs, I believe, are smaller,
and in doing a v6.5.x->v6.5.x+1 patch, are fine...context diffs contain
more "surrounding code", so that if someone else has made changes, the
patch command can generally find where the code has moved to.  That is why
we only generally accept context diffs for the source tree, since its such
a moving target...

And, if none of the above made sense, no worries...its barely making sense
to me too :(
