Take a look at the various option variables whose names begin with
"backup-by-copying".  The ownership change occurs because Emacs renames the
original file to the backup file and then writes a brand new file (which is
therefore owned by you).  If backup by copying is done, Emacs writes into
the original file, so the ownership doesn't change.

P.S. Please try to keep the lines in your postings under 80 columns wide.
