Subject: file-precious-flag breaks symlinks
Date: Mon, 28 Jul 2014 02:34:13 -0400

Package: emacs
Version: 24.3.92

touch foo
ln -s foo bar
emacs-24.3.92  -Q --eval '(setq file-precious-flag t)' bar
change bar and save
   -> bar is no longer a symlink

AFAICS, it has always (since at least 22.3) been like this.
Does it have to be, though? Why can't it overwrite the target of the link?

In any case, the doc only mentions breaking hardlinks.

Setting find-file-visit-truename non-nil avoids the problem.
