From 79ee194e52a140412da475e102145bad80d5d00a Mon Sep 17 00:00:00 2001 From: "Shawn O. Pearce" Date: Wed, 4 Apr 2007 11:19:14 -0400 Subject: [PATCH] Honor -p when applying git diffs If the user is trying to apply a Git generated diff file and they have specified a -p option, where is not 1, the user probably has a good reason for doing this. Such as they are me, trying to apply a patch generated in git.git for the git-gui subdirectory to the git-gui.git repository, where there is no git-gui subdirectory present. Users shouldn't supply -p2 unless they mean it. But if they are supplying it, they probably have thought about how to make this patch apply to their working directory, and want to risk whatever results may come from that. Signed-off-by: Shawn O.
