Re: PATCH: _ps1234, _date_formats: Complete strftime formats for %D{}

[Oliver Kiddle <okiddle@yahoo.co.uk>]

We normally leave configuration of colours for complist to the users but
in the case of the completion of terminal colours, I think the following
is useful. It is also one situation where we don't need to worry about
the user's colour preferences or even whether a particular colour is
visible over their background. Any thoughts?

I think the description of "ANSI" is only applicable to the first 8 (or
16 colours), right? This hasn't allowed for custom configuration of the
lc and rc in _comp_colors. Anyone know if there is a particular layout
of rows/columns that should be used so the colours line up logically?
Should we use set the background colour instead when completing within
%K{...}? (it seemed uglier to me).
