Yes, but I believe you get the one from @rev if you don't specify -r.

For example, I can ask for an "svn diff svn://blahblah@56
svn://blahblah@59" and it'll feed it to me as expected.

This is nearly the same as "svn diff -r56:59 svn://blahblah", except
that it might look for blahblah in different places, as you say.  I
tend to prefer the @notation for exactly at that reason.

File renames make diffing and merging complicated no matter whether
you track them or not.

svn's tracking of file identity is additional, but doesn't increase
the (UI) complexity in the common case.  At least with svn, a newbie
can even get real work done without even knowing about -r *or*
@notation.

Compare that to arbitrary differences in behaviour between "git-fetch"
vs "git-fetch a" vs "git-fetch a b", or the difference between HEAD^
and HEAD~1 and HEAD@1.  git is very powerful, but also definitely more
complex for beginners.

Have fun,
