From 8fdcf3125465f70c0cad5be5ab192d46e46307c7 Mon Sep 17 00:00:00 2001 From: Junio C Hamano Date: Fri, 29 Aug 2008 13:40:36 -0700 Subject: checkout: do not check out unmerged higher stages randomly During a conflicted merge when you have unmerged stages for a path F in the index, if you said: $ git checkout F we rewrote F as many times as we have stages for it, and the last one (typically "theirs") was left in the work tree, without resolving the conflict. This fixes it by noticing that a specified pathspec pattern matches an unmerged path, and by erroring out.
