bug#8963: 24.0.50; gnus-no-server tries to connect to IMAP server

[Daiki Ueno <ueno@unixuser.org>]

I have been using M-x gnus-no-server to reduce Gnus startup time when
using it off-line.  However, the current Gnus always tries to connect to
all the known servers on startup.  Here is my configuration (host names
are masked):

(setq gnus-select-method '(nnnil "")
      gnus-secondary-select-methods
      '((nnimap "a"
		(nnimap-address "a.example.org")
		(nnimap-username "daiki")
		(nnir-search-engine imap))
	(nnimap "b"
		(nnimap-address "b.example.com")
		(nnimap-username "dueno")
		(nnir-search-engine imap))))

Here is the log:
