I like this, and it's pretty much what I was looking for.  I only have
one criticism from a backend writing point of view: What happens if the
only return has been SANE_STATUS_GOOD?  Maybe just:

-----
This function returns a verbose description of the latest error, or an
empty string if no error has occured.

-----

Otherwise, perfect!
