bash: remove always true if statement from __git_ps1()
The recent commits 8763dbb1 (completion: fix PS1 display during a merge on detached HEAD, 2009-05-16), ff790b6a (completion: simplify "current branch" in __git_ps1(), 2009-05-10), and d7107ca6 (completion: fix PS1 display during an AM on detached HEAD, 2009-05-26) ensure that the branch name in __git_ps1() is always set to something sensible. Therefore, the condition for checking the non-empty branch name is always fulfilled, and can be removed. Signed-off-by: NSZEDER Gábor <szeder@ira.uka.de> Acked-by: NShawn O.
