	This is not a bug; do not apply the fix shown.  It is often
necessary/useful to create symlinks to files that do not (yet) exist.
We do it all the time for log files which can be removed by cron.  In
any event, the proposed fix would not prevent symlinks which point
at nothing as it is still possible to remove the pointed-to file
after the fact.  If you are really worried about this, modify ln(1)
to check for the source file, but don't bother posting the change.
