print theme('qform') doesn't work

Issue Summary

After some investigation I've found that theme_qform() is actually theme_question_qform(). Still, that function doesn't do anything, except when the user is not logged in (it prints the message "Please register or login to post questions")

There are then 2 problems:
1. readme.txt should follow the change from theme_qform to theme_question_qform
2. theme_question_qform() should do something...

How can I include the question form inside a node?

Thanks.
