From: Junio C Hamano Date: Sun, 10 May 2009 08:53:19 +0000 (-0700) Subject: completion: simplify "current branch" in __git_ps1() X-Git-Tag: v1.6.3.2~36 X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=ff790b6a4bb7fa3bbccd5ea23cefd89da900aa2e;p=git.git completion: simplify "current branch" in __git_ps1() As I very often work on a detached HEAD, I found it pretty confusing when __git_ps1() said 'some-name'. Did I create a branch with that name by mistake, or do I happen to be on a commit with that exact tag? This patch fixes the issue by enclosing non branch names in a pair of parentheses when used to substitute %s token in __git_ps1() argument. It also fixes a small bug where the branch part is left empty when .git/HEAD is unreadable for whatever reason. The output now says "(unknown)".
