Thanks nab. While looking at '--directory' I just found that there is a
'-p' option to both git-am and git-apply. It seems like it should do the
trick. Unfortunately even with that flag it still doesn't apply.

fatal: patch fragment without header at line 7: @@ -26,6 +26,9 @@

I think the problem is with the timestamp after the path that describes
the affected file. If I remove that timestamp I can get it to apply with
'git-am -p2'.
