Fairly old pull request from copperwater: add new paranoid_confirm
setting 'trap'.
The old commit suffered from bit rot and merging needed too much
fixing up despite there not being many bands of change in the commit's
diffs. I ultimately redid it from scratch, although the two biggest
chunks of code started with copy+paste of the pull request's commit.
It operates like paranoid:pray. Setting paranoid:trap adds a new
"Really step into <trap>?" y/n prompt when attempting to move
into/onto a known trap, even if an object covers it on the map.
Setting both 'paranoid:Confirm trap' turns that into a yes/no prompt.
(Adding 'Confirm' affects other paranoid confirmations; in addition
to requiring yes<return> rather than just y to accept, it also forces
no<return> to reject.)
However, moving into a known trap that is considered to be harmless
behaves as if no trap was present. Some of the trap classification
might be out of date; several types of traps have undergone changes
since implementation of the original pull request, notably anti-magic
field. When the hero is hallucinating, all known traps are considered
harmful since the map no longer reliably describes them.
Preceding a movement command with the 'm' prefix also behaves as if
no trap was present, bypassing confirmation for that move, similar to
how paranoid:swim currently behaves. Being stunned or confused also
behaves as if no trap was present, taking priority over hallucination.
This updates the documentation.
