Subject: [PATCH] am: read from the right mailbox when started from a
 subdirectory

An earlier commit c149184 (allow git-am to run in a subdirectory) taught
git-am to start from a subdirectory by going up to the root of the work
tree byitself, but it did not adjust the path to read the mbox from when
it did so.
