Documentation/config.txt: Fix documentation of colour config tweaks.

* The description of valid colour specifications was rather
incomplete, so fix it so that it actually describes colour specs as
accepted by color_parse().

* The list of colour items allowed in color.diff.BLAH was missing the
`commit' and `whitespace' entries.
