#2646: check_new incorrectly uses mh_seq_unseen Comment (by brendan): Reading over mh.c, the logic for reading unseen looks correct. But I did notice an off-by-one in mhs_alloc that looks like it could cause mutt to randomly discover new mail depending on whatever happened to be in mhs->flags[0] (which is never set). Does changeset [15f8a55220a7] fix the bug? -- Ticket URL: <http://dev.mutt.org/trac/ticket/2646#comment:2>
