Yet another round of fixing the Emacs manual

* doc/emacs/cmdargs.texi (Action Arguments): Rearrange text
describing what happens when Emacs is invoked with several file
arguments.  Suggested by Grant Rettke <gcr@wisdomandwonder.com> in
emacs-manual-bugs@gnu.org.

* doc/emacs/xresources.texi (GTK styles):
* doc/emacs/mini.texi (Passwords):
* doc/emacs/frames.texi (Scroll Bars): Use "cannot" instead of
"can not".

* doc/emacs/macos.texi (Mac / GNUstep Basics): Clarify the effect
of ns-right-alternate-modifier when its value is 'none'.
Suggested by Wanderson Ferreira <iagwanderson@gmail.com> in

* doc/emacs/calendar.texi (Importing Diary, Appointments): Now
sub-sections of Diary.
* doc/emacs/emacs.texi (Top):
* doc/emacs/calendar.texi (Diary): Adjust menus to the above
change.  Suggested by Isaac Carter <icarter1391@gmail.com> in
