It really should be documented, you're right (patches welcome, of
course!). I think the relevant place to look is here:

http://www.endrun.org/xr/svn/source/subversion/libsvn_subr/io.c, in
the function svn_io_run_diff() (begins at line 1702). The diff_cmd

   -L label1 -L label2 frompath topath

as arguments, it looks like. So you should write a wrapper script to
absorb the arguments you don't need and/or transform them into ones
you can use. The wrapper would invoke your real diff program.
