Has it really something to do with builtin-commands which do not change %ERRORLEVEL%?
I think the tests only cover one of those commands, a couple of additional tests would
probably not hurt. The lack of tests is also the reason why I haven't merged this into
Staging yet. If this turns out to be right way to solve it, I would suggest to define
a function check_errorlevel() which checks 'errorlevel' and 'changed' at once.
