Subject: [PATCH] fix github issue #511 - no death message when

level-drained below level 1.  No "you die" or equivalent, just
straight to being life-saved or to "do you want your possessions
identifed?".  Change it to issue "Goodbye level 1."  The fact
that it is has been fatal will become obvious.  An issue comment
on github pointed out where the fix was needed.

Fixes #511
