PR 1078 (yes, that is a very old issue) notes that there is no
documentation for the C++ "com_interface" attribute. In fact, this
attribute has done nothing but issue a warning saying it is obsolete for
almost 15 years (r42465, to be exact). It is hard to imagine that
anyone is using it any more, so I think we should just delete it
entirely instead of documenting it. OK to commit?
