Comment 5 for bug 2065120

I decided this deserved its own issue:

====
2067412: When a Tag is copied, multi-valued attribute value lists are not deeply copied

Putting this bug aside, is my understanding correct that for BeautifulSoup tag objects, copy.copy() and copy.deepcopy() both always result in a deep copy?
