If git am fails to apply something, the end user may need
to know where to find the patch.  This is normally known for
a single patch, but if the user is processing a mbox with
many patches, they may not have a single broken out patch
handy.  So, provide a helpful hint as to where they can
find the patch to do some sort of manual fixup, if we
are processing a mbox with more than one patch in it.
