From c8183cd2851965665655738fc399c44f546d5b79 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Nguy=E1=BB=85n=20Th=C3=A1i=20Ng=E1=BB=8Dc=20Duy?= Date: Wed, 13 Mar 2013 18:42:53 +0700 Subject: branch: show more information when HEAD is detached MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This prints more helpful info when HEAD is detached: is it detached because of bisect or rebase? What is the original branch name in those cases? Is it detached because the user checks out a remote ref or a tag (and which one)?
