Revision 47ee06f1224cc355d0d5fffb0a65b831790b2845 authored by Jeff King on 05 January 2008, 09:57:44 UTC, committed by Junio C Hamano on 07 January 2008, 02:41:44 UTC 
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.
