Description
--extensions '' doesn't work. If the user tries to set diff options to nothing (''), svn ignores it entirely,
and uses -u. This is broken for programs like bbdiff and sdiff, which don't support -u.
Using a non-empty string, --extensions can be coaxed into dropping -u, but still supplies -L, which
also prevents usage of bbdiff and sdiff. I have confirmed this behavior in both Mac OS X 10.3.5 (built via
fink) and FreeBSD 4.10-STABLE (built from ports).
