[PROPOSAL] sane log/diff behavior on single revision (was: svn commit: r31104 - trunk/tools/client-side)

This was obviously a good change for showchange.pl. I'm wondering if it
might be a good idea for the command-line client too!

Right now, if you run 'svn log -rNNN' or 'svn diff -cNNN' in a working
copy directory, you may or may not get all of rNNN, even though rNNN was
committed in that repository.

   1) If rNNN was committed to some other branch, and never merged to
      this working copy's branch, then you'll get no output (well,
      you'll get a "------------" line in the case of log, but that's
      the same as getting no output).

   2) If rNNN was committed above the current directory, but includes
      some stuff in or under the current directory, then you'll see that
      subset of rNNN, but not the whole thing.

   3) If rNNN was committed to some other branch, but merged to the
      branch for which cwd is a working copy, then you'll see rNNN,
      except perhaps as adjust according to (2).

I think that's all more or less correct. Can you keep it straight? I
sure can't. I'm not even sure about the last part of (3), but I'm not
going to bother to test it, because I have a better behavior to propose
anyway:

   If the user explicitly requests a single revision but not a path,
   then show all of that revision, by using cwd's "Repository Root"
   as the URL.

Would that *ever* be the wrong thing to do?
