Presumably you're executing that command in a working directory,
checked out from one of those branches.

What the command means is: tell me the differences for the files in
THIS directory and its children (i.e., in the branch for THIS
directory) between the two revs mentioned.

If you made no changes in this branch between those two revs, you will
not see anything.

I think you're suffering from the CVS version conceptual mixup. A
subversion revision number isn't a revision number of a part of the
repository (for example, a given branch). So your first paragraph
isn't correct in Subversion. The correct statement would be:

  I have two branches by different names. One branch was last changed
  in repository rev 15; the other was last changed in repository
  rev 12.

In other words: for the second branch, that subtreee of the repository
is unchanged between revs 12 and all later revs.

---
Now to what you probably meant to do:
If you want to see the difference between two branches, do this:
   svn diff svn://hostname/repos/branches/branch1 svn://hostname/repos/branches/branch2
That will compare the latest version of branch1 with the latest in
branch2.  If you want to compare earlier versions, add @version to one
or the other URL, as needed.
