Do you set `diff-switches' to "-u1" ?
This call:
(vc-switches 'RCS 'diff)
in `vc-rcs-diff' uses `diff-switches', and passes the result to "rcsdiff".
Not sure what to do here. We already have a bug:

Karl Berry
You're completely right (I did that umpteen years ago). Sorry for
wasting everyone's time.
#4422: diff-switches is a bad idea
Despite my own bug, I don't agree it's a bad idea.
