I've just installed a patch to deal with this. It uses the same
mechanism that VC already uses to find out if rcsdiff understands the
--brief option. VC will first try to use -L, and then remember whether
it worked in the new variable vc-diff-knows-L.
The patch assumes that a "diff" that does not understand -L returns
error code 2 when the option is used. I have not been able to verify
this with Solaris 8 diff, but I'm pretty sure that this is how it's
reported.
If anybody sees a more elegant way to implement this, please don't
hesitate to change it.
