Okay.  However, if the current code were working correctly,
then there is a little time between the unlink of the symlink
and the open(O_WRONLY | O_CREAT | O_TRUNC) of the file to be
written.  So there is a window for someone to quickly recreate
the symlink.  So --nofollow would give a false sense of security.

Also, is there any other editor that has this feature: overwrite
symlinks instead of following them?
