Yes, you are right.

What I do not understand is, why does it not work like that:

svn diff uses internal diff
svn diff uses diff-cmd if specified in the config

svn diff -x -p uses internal diff.
Why? it should call 'diff' from the $PATH, I would assume that -x
implies 'external', either from PATH or from config.

An odd thing:
svn diff -x -puBbw --diff-cmd true -r 5411:5418 subversion/tests/clients/cmdline/commit_tests.py
Index: subversion/tests/clients/cmdline/commit_tests.py
===================================================================
svn: Error calling external program
svn: 'true' returned 255

true -puBbw -L 'subversion/tests/clients/cmdline/commit_tests.py (revision 5411)' -L 'subversion/tests/clients/cmdline/commit_tests.py (revision 5418)' tmp tmp.2 ; echo $?
0

Is there a reason why -x does require --diff-cmd if no diff-cmd is
specified in the config file? I would call that a bug.
