[Message part 1 (text/plain, inline)]

Hello,

This is a feature request. Emacs currently displays three months in
the calendar, and it is useful to show more months when the
window/frame is wide or when users need a larger calendar range.

This patch allows users pressing '+' to display more months at the
right side of calendar if there is enough space, with an upper limit
of 12 months.

All scroll/motion commands should work well. Some commands, such as {
or }, cause the cursor jumping back and forth. This patch changes the
behavior of these commands to match that of calendar-forward-day
(C-f), which feels more natural when there are more months.

If it is acceptable, I'll add holiday support for extra months and
update the documentation later. Feedback is welcome.

Hi Liu,

Here is some feedback from my quick testing of your patch:

     - I think that C-v/M-v should scroll of the amount of displayed
       months and not just 3.

     - After some movements with C-v/M-v, hitting '.' does not move the
       cursor to today (maybe this is not related to your patch).

     - Regarding the messages about the number of months, I think it
       should be "The calendar shows at least 3 months." and "No space
       left to display more months." (instead of "There is no space.")
