Ok, I did some more testing. It may be that this existed in the first
svn I used (v1.2.3). WIth -x it works in v1.4.4, at least in the
sense that the -u goes away.

However, the -L does not go away, and xxdiff doesn't like -L either.
I think minimally there needs to be a way to say "don't give me ANY
switches". More general would be a way to specify what switch token
to use for what purpose. For example xxdiff wants --title1 and
--title2 rather than the first and second -L.
