run-tests: don't add python lines to expected dict

For test input lines of *.t files starting with '  >>> ', the code block for
'  >>> '

609:        if l.startswith('  >>> '): # python inlines
610:            after.setdefault(pos, []).append(l)

was (unsurprisingly) executed, but because there was an "if" instead of an
"elif" on the condition "l.startswith('  ... ')", program execution proceeded
to line 636

635:        elif l.startswith('  '): # results
636:            # queue up a list of expected results
637:            expected.setdefault(pos, []).append(l[2:])

due to the fact that if l starts with '  >>> ' it also starts with '  '.

The net effect was that python command lines in *.t files were (surprisingly)
also added to the "expected" dict.

This caused no externally observable bad behavior, as the "expected" dict was
not consulted for these lines.
