From f6ce1f25885f3db71935b201c5e3c858eb993f5c Mon Sep 17 00:00:00 2001 From: Jonathan Nieder Date: Sun, 31 Oct 2010 14:59:33 -0500 Subject: [PATCH] cherry-pick/revert: transparently refresh index A stat-dirty index is not a detail that ought to concern the operator of porcelain such as "git cherry-pick". Without this change, a cherry-pick after copying a worktree with rsync errors out with a misleading message. $ git cherry-pick build/top error: Your local changes to 'file.h' would be overwritten by merge. Aborting. Please, commit your changes or stash them before you can merge.
