nil is a lot of things, it is the boolean false, it is
a variable with a value that isn't ready to be used, it is an
empty list, and apparently and empty string as well:
(string= "" nil)
Thanks for mentioning `string-empty-p' BTW, didn't know of
that, now I can remove my own `empty-string-p' :P
(which shows the same bahavior BTW)
