Re: Suggested new feature for rcsdiff

[Karl Berry]

    I'm not sure what the best syntax would be.  Ideally, it should be
    easy to specify multiple arguments, but still possible to specify
    a single argument that contains white space.

Yes.

FWIW, I suggest
-Xopt arg1 -Xopt arg2

I just invented this for a forthcoming new program in Texinfo that needs
to be able to pass arguments to subprograms.  I chose the name "-Xopt"
because it was generic, hence could conceivably be used across programs,
but inspired by the -Xlinker option in gcc.

I think repeating and accumulating args is better than the comma form,
in principle, because what if you want to pass an argument containing a
comma?  Complexity, in one form or another, so why not avoid it from the
start ...
