BBDB's context is that bbdb-anniv-diary-entries is added to
diary-list-entries-hook (which is run when diary-entries-list is
properly bound).  The function bbdb-anniv-diary-entries then calls
diary-add-to-list.  This approach has been used by BBDB for 15
years and I believe that quite a few people have liked this.

No matter whether you consider this approach clean or not, I think
it is reasonable to have *some* mechanism for adding diary entries
from other sources than just diary files.

Well, it would be nice to have some mechanism to let the external
source of diary entries define what should happen.  I mean, in the
case of BBDB this is obvious: when pressing "d" this should then
jump to the respective BBDB record.

I don't know whether it makes much sense to jump to an entry in such
an auto-generated file.  I'd be rather confused.
