Subject: git-merge-one: new merge world order.

This does two things:

 - Use new --stage=2 option to create the working tree file with
   leading paths and correct permission bits using
   checkout-index, as before.

 - Make sure we do not confuse "merge" program when the file
   being merged has an unfortunate name, '-L'.
