Well, if we use something like _diff_is_gnu[$words[1]], using a
non-local variable should be fine, right?

But you are right -- I had forgotten to integrate using $words[1] into 
my suggestion somehow. Hm.

Still no patch for any of this, though. The problem is that this would
probably be interesting in several places so that updating the docs
would be quite a bit of work. And since we also had the `discussion'
about trying to add some auto-documentation mechanism (using magic
comments in the functions) I wanted to delay it until we had thought
about that some more.
