Basically for the following reason: users may expect -c to use the
same arguments as -r since -cREV is a shortcut for -rREV-1:REV. As I
said in a previous post it occurred to me to type "svn di -cHEAD"
after I've seen someone committing on #svn-dev. It may be me being
lazy to type the rev in, but I think I've wanted this feature for the
sake of homogeneity between options. I understand this might not be
the most used feature ever.

That's what the patch is implementing, yes. As you point out, using
-cHEAD will be a no-op when executed in a sub-directory (branch or
whatever) below which no change happened. But when executed from the
very root of the repository or when passing it as target (could be
../../ as much as http://path/to/repos), it will always return some
bytes.
