Haha!  Tough!

That'd be nice, but probably harder to convince them than for
XDG_DATA_DIRS, as we'd probably be the only user.

Yes, more complexity, but localized (and can be tested), rather than
diffused (and untested) as of now.

Perhaps this could work too, *if* the behavior of various same-named
environment variable specifications is to be combined into a logical OR
manner (I haven't checked what the current behavior is, but I seem to
recall it not working from past experiments).

Thanks,

Maxim
