From: Junio C Hamano Date: Mon, 25 Jul 2005 20:05:44 +0000 (-0700) Subject: Use symbolic constants for diff-raw status indicators. X-Git-Tag: v0.99.2~3 X-Git-Url: https://git.verplant.org/?a=commitdiff_plain;h=e7baa4f45f4420a6d2da6a13e8959f8405c3ea19;p=git.git Use symbolic constants for diff-raw status indicators. Both Cogito and StGIT prefer to see 'A' for new files. The current 'N' is visually harder to distinguish from 'M', which is used for modified files. Prepare the internals to use symbolic constants to make the change easier.
