The bug was caused by the script not not allowing for the cases when
either the expected or computed returns from the doctests were empty. The
attached patch does this properly and also cleans up the script a little.
Note that the script lives in $SAGE_ROOT/local/bin which is probably not
part of the standard repository. As this is a script run by sage, rather
than a part of the sage library, I don't see any way to doc-test it.
