Well, once again, we have two camps.

A bunch of people claim that examining local diffs iteratively is
their primary use-case of 'svn diff', and a different bunch of people
say the primary use-case is for comparing two named objects. I'm not
sure how to resolve this.

Ghudson did make a good point about 'svn diff' not necessarily losing
the -r flag.

Either way, I can't *possibly* imagine adding a 5th use case to 'svn
diff'. It's already ridiculously confusing. All you people
advocating that we add more switches -- you don't think this is true?

This is why I was supporting cmpilato's proposal to create a new
subcommand. Brian Denny objected to naming it 'compare'... but forget
about the name for moment. Suppose we call the new subcommand
'zort'. What I'm pushing for is the KISS principle. Suppose you need
to explain differencing to a complete svn newbie. I like this

   "If you want to see your local changes, run 'svn diff'. If you
   want to compare any two things, run 'svn zort'."

At the moment, there *is* no reasonable way to explain 'svn diff':

   "If you want to see your local changes, run 'svn diff' with no
   arguments. If you want to compare any two things, then start
   adding -r switches (with either one or two revisions), or @
   switches attached to urls, [or possibly an --incremental option.]"
