Yes, it's been discussed many times on the dev@ list. Nobody's ever
bothered to implement it yet.

I'm looking at

BASE means, "the file's revision in your working copy". If you run
'svn info foo.c', that's the number you'll see. 'svn status -v' also
shows that in the first revision column.
COMMITTED means, "the last changed revision" of the file. There's even
a $LastChangedRev$ keyword for this. 'svn status -v' shows it in the
second revision column.
Here's a real simple example. You checkout a working copy of r5, so
everything in the working copy is at r5. Now your friend commits a
change to foo.c in r6. You update again, and now your whole working
copy is at r6. That is, every file has a BASE revision of 6. If you
look at foo.c, it's 'last changed revision" (COMMITTED) is r6. But the
other files all have different 'last changed revisions'... things less
than 6.
PREV is just defined to be COMMITTED-1. Which means at any time, 'svn
diff -rPREV:COMMITTED foo.c' will show the last change somebody made to
the file.
