I just used the Windows UI to rename a file to ".exe" and it works fine (both
renaming and susbequent execution of the file from the command-line).
Meanwhile, the documented behaviour of `stem` is that something containing only
a single dot will result in an empty string, which I think we should be
mirroring here. I think the behaviour tested here is therefore correct and you
can probably drop the TODO note.
