I found out what's happening with `q': when I do `emacsclient -c', the
frame initially shows only the *scratch* buffer. I now type `M-x
calendar', which as usual splits the screen vertically, with the
*Calendar* buffer below and *scratch* above. Now type `M-:
(calendar-window-list)': it returns (something like) "(#<window 8 on
*Calendar*> #<window 4 on diary>)", and indeed `C-x C-b' reveals that
the diary buffer is a live buffer. So when I type `q' in the *Calendar*
buffer, calendar-hide-window is applied to the unseen diary buffer and
to the displayed *Calendar* buffer, which explains my observation. What
remains to be explained, and fixed, is why the diary buffer is not in a
displayed window, although its window is in calendar-window-list. I
think this has to do with --daemon, because when I start Emacs without
--daemon but with the same ~/.emacs, then the diary is initially
displayed below and the splash screen above; but with --daemon neither
of these is displayed upon invoking `emacsclient -c'.

Sorry, I gave the wrong recipe: after invoking `emacsclient -c', just do
`C-x b diary' and you should get the diary buffer with the truncated
mode line.

Thanks for removing this too. I think your comment in calendar.el on
this point probably has wider application:
;; They also used to check display-color-p, but that is a problem if
;; loaded from --daemon. Since BW displays are rare now, this was
;; also taken out. The way to keep it would be to have nil mean do a
;; runtime check whenever this variable is used.
Cf. also bug#2138 and Dan Nicolaescu's remark:
