Creating an empty tag renders TAB-completion useless.
Example:
* Title :a::b:
Pressing TAB in org-set-tags-command will now insert a colon `:`, which is quite puzzling to see.
I thought something was wrong w/ my bindings till I noticed this was happening only in one of my files.
Can such tags be ignored/disallowed as they hold no evident purpose?
