FTLIW, if a change is made (and I can see why it might be desirable,
just for full accuracy if nothing else), I'd support this - on
condition, as I've said before, that we make the fact that a default can
be specified in the config file explicit in the documentation.

I'd take this as a fallback - some variant of any of B, C or D, but not
A because it's too generic.

If we were supporting only OSes (or, rather, programs on those OSes)
which don't attach any special significance to "filename extensions",
this would be simply a variant of option 2. As things stand, I don't
think it's really a good alternative.

There is, of course, a fourth possibility, even though it may be too
difficult to code feasibly at this stage: detect the file type and
determine the default filename (or, rather, the default extension) based
on that. I don't expect anyone to support that unless they're willing to
do the work necessary to code it, but the option does theoretically
exist, and it is in principle probably the most correct way.
