Open the following file in emacs (emacs -Q sh-bogus-comment.sh):

--8<---------------cut here---------------start------------->8---
#!/bin/sh

do_untrusted()
{
  : ${squash:="squash_uids=0-149"}
  for host in $pc_untrusted; do
    # force `ro
    echo "  $host($squash,ro,sync)\\"
  done
}

while read dev point rest; do
  case $point
  in ( /Disks/var )
    echo "$point \\"
    rw_ro=rw do_hostlist
    echo
    echo "#"
  ;; ( * )
    :
  esac
done < /etc/fstab
--8<---------------cut here---------------end--------------->8---

The buffer is font-locked incorrectly, see the attached screen shot:

It seems like the unbalanced backquote in the comment «# force `ro» in
combination with the two «echo "... \\"» confused font-lock.
