You could put a breakpoint on call-process and examine its arguments,
for example.

Why do you use --diff-options?  "bzr diff" works as if -u was
specified anyway, and will use its internal emulation of Diff if you
don't pass --diff-options.

Only if you use --diff-options.

That's probably related.  So restore your diff.exe, and things will
work again.  They do for me, because my diff.exe is in perfect working
order.
