pull request #976 - D of AP

Pull request from entrez:  combining just-picked-up (P) with explicit
accept without confirmation (A) for multi-drop (D) ignored the
just-picked-up part and dropped everything.

Affects menustyle:Full.  For menustyle:Traditional, 'A' operates very
differently and combining 'a' with 'P' or vice versa already does the
right thing.

Closes #976
