Since this trick is not very intuitive, I'm wondering what's wrong
with something easier to remember (and to explain!) such as:
:0:
* LASTFOLDER ?? .+
{
...etc.
Am I missing something?
Well, the '+' is unneeded (though it shouldn't cost you anything), but
yes, that should work just fine. (You also can't have a locallockfile
on a non-cloned nested block.) The only differance is that the ${LF+!}
trick will work even if the variable is empty, but set, which shouldn't
matter in the case of LASTFOLDER. There may be a speed differance, but
I could see it swing either way.
If nothing else, ${LF+!} has more hack value. ;-)
