The code in basic-save-buffer that deals with file-precious-flag does
(what I think is) the wrong thing with links.  Because of the way it
tries to preserve the old file, you lose if it was a link (you get a
copy).  Doing this right seems rather complicated because it probably
needs to look at the backup-by-copying* flags and notice when there is
a link and follow it and stuff.  For now I have offered the user that
had the problem the solution of making the file not be precious (it's
RMAIL that it happens in, I just wrote them an rmail-mode-hook).  This
isn't really the right thing though.
