Hmm, interestingly, if you do _not_ stage the changes (i.e., drop the
final "git add" there), you get:

  $ git stash pop
  error: Your local changes to the following files would be overwritten by merge:
	test
  Please, commit your changes or stash them before you can merge.
  Aborting

which makes sense. Writing conflict markers into the file would leave
you in a situation where it is hard to recover the "bbbbb" content.

But we seem to skip that safety valve when the content has been staged,
which seems questionable to me (technically we are slightly better off
than the protected case because "bbbbb" was written to a git blob
object, so you can recover it.  But it may be difficult to find the
correct blob in the object database).
