bug#3338: 23.0.93; Celendar C-f fails at the end of the buffer

[eythanweg@gmail.com (Eythan Weg)]

Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your bug report will be posted to the emacs-pretest-bug@gnu.org mailing list.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

Start calendar.  Make sure June is on the right
side of the buffer.  Move cursor to June 30. Press
C-f.  Result:  June moves one month to the left,
the cursor remains on June 30.  I expect it to
move to July 1.  This happens starting with emacs  -Q.



If Emacs crashed, and you have the Emacs process in the gdb debugger,
please include the output from the following gdb commands:
    `bt full' and `xbacktrace'.
If you would like to further debug the crash, please read the file
/home/weg/sources/emacs/etc/DEBUG for instructions.
