missing svn diff -p, -c

'svn diff' appears only to be capable of generating "unified diff"
format, i.e. equivalent to diff -u. This is a good default, but I
find myself missing two other modes of the standalone diff:

1) -c format, which prints each chunk as it was marked up with ! and
   - indicators, then as it is now marked up with ! and + indicators.
   For some changes this is substantially easier to read than -u format.

2) -p / --show-c-function: in conjunction with -c or -u, this tacks
   the name of the enclosing C function, if any, onto the end of each
   @@ -x,y +a,b @@ line. Extremely helpful when writing GNU-style
   changelogs (which require you to mention the name of each changed
   function).

If I could have just one of these, I'd far rather have -p than -c; but
both would be useful. (-p is crucial to my normal working habits, and
I am resorting to "diff -up .svn/text-base/$file.text-base $file" in
its absence.)

In a related observation, I can't get svn diff -x to do anything
useful. Whatever I put after the -x, I get a "not supported" message.
