[New-bugs-announce] [issue6045] Fix dbm interfaces

I disagree that this is release-critical. I think it is desirable to
say that the dbm modules support most of a dict-style interface,
and I also think that it is factually correct to claim that they
currently do.

The problem with the current documentation is that it apparently stopped
documenting the "dict-style interface", in the sense

http://www.python.org/doc/2.5/lib/typesmapping.html

did. Instead, the documentation now only documents the dict type itself.
If a dict-style interface was specified, one would have to specify
whether returning views from keys/values/items is part of the dict-style
interface or not.
