Subject: Discard stderr when determining if a patch is already applied
X-Git-Tag: v0.14~96
X-Git-Url: https://www.chiark.greenend.org.uk/ucgi/~mdw/git/stgit/commitdiff_plain/5dfab1742228a9fd237cc124943fcab6d7e9b40a

Discard stderr when determining if a patch is already applied

An error from git-apply just means that the patch isn't applied.
