Yep, makes sense.

It's a shame we can't use the slightly more readable OPT_FILENAME(), but
it forces the use of "file" for the argument name. I wonder if it really
ought to be OPT_PATH(), and say "path", which would work more
universally.

At any rate, I'm fine with this until somebody feels like fiddling with
the macros.
