Document the color.interactive semantics
There are two possible confusions with the color.interactive
description:
1. the short name "interactive" implies that it covers all
interactive commands; let's explicitly make it so, even
though there are no other interactive commands which
currently use it
2. Not all parts of "git add --interactive" are controlled
by color.interactive (specifically, the diffs require
tweaking color.diff). So let's clarify that it applies
only to displays and prompts.
