score 0 but no warning

[jnorell]

I don't know if this is a bug or my misunderstanding of the comment in the example, 'echo $weak['feedback']['warning']; // will print user-facing feedback on the password, set only when score <= 2', but I tested with a dictionary word and got back a score of 0 with no warning set:

'''

In our project I made the error to check if feedback warning was set as an indication of a score <= 2, so this allowed bypassing the dictionary check - clearly my error, but maybe is a condition that wasn't supposed to happen?
