issue of gnus daemon

[Binjo <binjo.cn@gmail.com>]

hi,

i use gnus demon to retrieve mail, and my settings as follows:

#v+
    ;; idle 2 minutes, then check news every 3 minutes.
    (gnus-demon-add-handler 'binjo-gnus-group-get-new-news 3 2)
#v-

it turns out the recent changes do not obey what the info said.

M-: (info "(gnus) Daemons")

#v+
   If IDLE is a number and TIME is a number, the function will be
called every TIME minutes only when Emacs has been idle for IDLE
minutes.
#v-

wheras from the *imap log* buffer, i can confirm it runs
`gnus-demon-run-callback' exactly every 3 mins, no matter emacs is idle or
not. that's weird.

09:39:00 202 UID FETCH 1:* FLAGS
09:39:00 203 EXAMINE "Dropbox"
...
09:42:00 272 UID FETCH 1:* FLAGS
09:42:00 273 EXAMINE "Dropbox"
...
09:45:00 342 UID FETCH 1:* FLAGS
09:45:00 343 EXAMINE "Dropbox"
...

i'm not able to figure out where's the problem though :<

the following patch resolve issue when using such daemon handler anyway:
(gnus-demon-add-handler 'binjo-gnus-group-get-new-news nil 2)
