more PR #1051, take II

I realized that the previous attempt was misusing the item's locked
state when attempting to create the chest that the item would go into,
which was absurd.  I hadn't realized that I was also misspelling
"olocked" as "locked".

This fix was already in progress before the mail about the previous
commit.  I did try switching to 'lckd = nil' for the attempt to retain
the chest's random locked/unlocked state but that resulted in all the
chests being created locked.  Using separate box=... expressions does
work as intended.  Doing something with totable() doesn't seem to be
necessary.

The indentation seems to be messed up compared to the rest of the
file (initial indent of 5 with increments of 4 rather than 3 and 3);
I have't done anything to try to fix it.
