When you have resolved this problem, run "git am --continue".
If you prefer to skip this patch, run "git am --skip" instead.
To restore the original branch and stop patching, run "git am --abort".
Obviously I could fix this manually, but if there's something wrong
with your patch posting process, we should fix it.
