PATCH: fix uses of literal % characters in completion descriptions

[Oliver Kiddle <opk@xxxxxxx>]

With some helper functions like _description and _arguments, the
descriptions pass via zformat so care is needed to double any %
characters to avoid them being interpreted.

I found some where where an intended literal % is getting lost and a
couple of functions that use %B...%b for bold rather than leaving that
to user style preferences.
