Revision ae5d8470f6b8e1abdef19bf033472c63fb72b735 authored by Marco Roeland on 05 April 2006, 20:28:28 UTC, committed by Junio C Hamano on 05 April 2006, 21:07:21 UTC
The "--amend" option is used to amend the tip of the current branch. This documentation text was copied straight from the commit that implemented it. Some minor format tweaks for asciidoc were taken from work by Francis Daly in commit b0d08a5.. It looks good now also in the html page. [jc: amended further to follow the recommendation by Francis in commit 3070b60]. Signed-off-by: Marco Roeland <marco.roeland@xs4all.nl> Signed-off-by: Junio C Hamano <junkio@cox.net>
