You're quite right - in CVS, different variants of the program are
implemented using branches, which are part of the revision number
space and so can be referred to with the -r argument to diff. That
doesn't work in Subversion because variants appear in the space of
paths. So you need to be able to pass those on the command line.

(Sorry to state the obvious. Just a long-winded way of agreeing.)
