Re: HEADS UP: Largely rewritten gnus-agent implementation.

[Danny Siu <dsiu@adobe.com>]

I am only using nnnil as primary and nnimap as secondary backend.  I removed
all .fetched files, did a 'gnus-agent-regenerate', and 'J s'

- gnus-agent-regenerate seems to do the right finally: it recreates
  .agentview based on articles that have already been download on disk. This
  alone saved me hours of agent refetching time!  Thanks for making this
  works.

- i have (setq gnus-agent-mark-unread-after-downloaded nil) but sometimes
  articles are marked read ('O') after being splitted to the its destination
  group.

- .agentview files may contain bogus info, like "nil 2" etc.  (or it has a
  new format now?)

- i am seeing all my dormanted articles became read (marked 'O')!!!  I know
  that nnimap stores gnus specific marks, like dormant, on IMAP servers that
  support custom marks.  this is a major problem for agent right now.

agent is working much better than before and i am seeing some operations are
much faster too.  

thanks for the good work, Kevin and Kai!
