I've been wanting to modify write-file, to make it ask the user if a
non-existing directory should be created, rather than throwing an
error about it, but wanted to see what other folks would say about it,
before submitting a patch for it.
it would be a minor change; would there be any problems with it?
i'd thought of making it ask the user only when (interactive-p);
probably will, unless there's a good argument against it.
