Fix the problem From a bug report. Presumeably the corpse exclusion at <u.ux,u.uy>
was intended to be for killing your way out of an engulfer, but there wasn't
any comment to that effect. The exclusion still applies if you were inside
the monster when it died; ridden steed is the only other way I can think of
to have a monster die at your location, so it should be the only case which
gets affected. Neither steed nor engulfer is allowed to generate a random
item when upon death; you already know what was carried in those cases.
The bulk of the diff is from reorganizing the relevant `if' and
subsequent indentation changes.
