Bug Report
Function: shipdamage()
Export Version: Jun 9, 1984.

  I was looking through the `shipdamage' function from
  "Export Version of Jun 9, 1984" and noticed that the
  items in `shp_v[]' are not `correctly' damaged.

  Each entry in `shp_v[]' should be checked to see whether
  it is an item using vchrstr, (vchr[type].vch_flag == VCH_ITEM),
  which then implies that it can be damaged.

  In fact, whatever sector currently resides in `sect' is
  indexed to get the type rather than the ship structure.
  The index range is correctly obtained with respect to the ship
  in question but `sect.sct_v[i].v_type' is indexed rather
  than `shp->shp_v[i].v_type' for the entry type.
  
  This implies that some unrelated type is obtained and if it
  should be an `item' then whatever is contained at that index on
  the ship will be damaged. Naturally the items damaged on the
  ship will not follow a logical pattern, and should the type
  field of whatever is in `sect' contain a bizarre value, then
  the indexing of `vchr' will be out to lunch.

  I should expect such an obvious bug has been fixed in later
  releases...

This reminds me of a bug associated with sailing over mines. I don't know if
it was ever fixed. If your ship was damaged below 20% it kept sailing until
it ran out of mobility. Only when you stopped with 'h' did it sink.
And if you killed the process, the damage was never inflicted.
