Thanks again, and sorry to leave this hanging.  I had some vague ideas
for improvement:

 * style nits: test is a little long, making it hard to take in at a
   glance; tests tend to try to avoid pipelines to avoid losing the
   exit code from git commands; usual style is to use "test" instead
   of "[" consistently

 * would be nice to have another test that makes sure the "move a
   file, not submodule" case keeps working

But those can easily happen as changes on top, and as you mentioned,
it's probably worth someone interested (e.g., me :)) making a pass to
clean up the style of the rest of the script anyway.

The patch as-is is obviously good.  Thanks again for the quick
diagnosis and fix.
