[sup-devel] [PATCHv4] [issue14] poll updates accumulate while idle

[Eric Sherman <hyperbolist@gmail.com>]

If you were to leave sup running for a long time, this patch would
enable you to get a glance summary of new mail activity since sup was
last touched, by letting the poll update message accumulate its tally
while idle.

This patch depends on [PATCHv2] idle and unidle updates.
