diary-redraw-calendar clobbers point in diary-file buffer.

[Matt Hodges]

In GNU Emacs 22.0.50.8 (i686-pc-linux-gnu, GTK+ Version 2.6.2)
 of 2005-03-04 on dugong
Distributor `The XFree86 Project, Inc', version 11.0.40300001
configured using `configure '--with-gtk''

Recent code has added diary-redraw-calendar to
write-contents-functions in the buffer associated with diary-file.
However, this function doesn't preserve point, and it gets clobbered
in mark-diary-entries (provided mark-diary-entries-in-calendar is
non-nil, of course).

Suggested patch attached.

Thanks.
