[PATCH/RFC] git-am: Make it easier to see which patch failed

["Jonas Flodén" <jonas@floden.nu>]

When git-am fails it's not always easy to see which patch failed,
since it's often hidden by a lot of error messages.
Add an extra line which prints the name of the failed patch just
before the resolve message to make it easier to find.

How about this instead. Though the line could get very long.
This makes the line stand out a little more.
