The comment '# Ignore dangling symlinks for now' seems pretty
self-explanatory to me...  try this:

# touch thing
# ln -s thing thing2
# [ ! -f thing2 ] && echo "thing2 doesn't exist"
# rm thing
# [ ! -f thing2 ] && echo "thing2 doesn't exist"
thing2 doesn't exist
#

It is just skipping any links in rc?.d where the 'real' file linked to
has been removed from /etc/init.d - this is something in the nature of a
sanity check.
