This is not an edge case for me. I have a lot of empty directories. In
the ideal world ido or helm would just squash them.

Yes, this is true, if the number of files is large. For small numbers
you can see the options, for large numbers this is truncated.

Okay, that's a good explanation!

Well, we both having the confounding factor that I am used to
del/tab/ret and you are used to C-j/C-l. None the less, I would argue
that single key presses are faster than doubles, especially for
tab/del/retn which everyone uses a lot and are nice and big.
