From: Junio C Hamano Date: Sat, 23 Jul 2005 02:08:47 +0000 (-0700) Subject: [PATCH] git-branch: avoid getting confused by empty or nonexisting branches. X-Git-Tag: v0.99.2~31 X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=a38e727925bfad369fc98165f6ff161193397f28;p=git.git [PATCH] git-branch: avoid getting confused by empty or nonexisting branches. When not specifying the start point explicitly, we ended up emitting ^0 in addition to the default HEAD. Be careful to see if we have "$2" before finding out which commit to base the new branch on.
