I don't like the idea of changing assoc-string to also match symbols.
Maybe it won't lead to any catastrophe, but it just sounds wrong.
I don't like the idea of adding "" at the beginning of a completion table.
Here I have a good reason, which is that it changes the behavior:
(try-completion "" '("aaa" "aab" "aac")) => "aa"
(try-completion "" '("" "aaa" "aab" "aac")) => ""
Honestly, what's so great about being able to use lists of symbols rather
than lists of strings? In Emacs-21, we don't even allow lists of strings,
but only lists of pairs whose car is a string, and people haven't complained
about it.
