"That's not true, ..."

It appears I missed the test data:

qw{ abc ab12c 2345 234y 01234 }
[download]

from johngg's post.

I've rechecked and I'm pretty sure that's the only one with test data not containing only digits.

"All others work with any passwords."

While that maybe true, I've no idea why you thought it was important to state it. I made no reference to what code did or didn't work. I did comment on test data.
