Clarification needed for OnlyShowIn and empty list
Submitted by Frederic Crozat Crozat

There is currently no way to hide a .desktop file from both menu in desktop environment AND menu editors (NoDisplay only hides in desktop environment).
Using OnlyShowIn=; is not considered as valid by latest version of desktop-file-validate.
So, we should either enable this case or add a None keyword (or X-None for backward compatibility maybe).
