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

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 [email protected] 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.
