Idepth is the depth to search to in multiples of DEPTH.

So Idepth=48 (DEPTH=12) means this is the 4th time searching
through iterate, and we should search 4 ply (plus extensions).

Outside of output handling, the code should avoid the division -
I think two exist - I'll look at them but I don't think either
is performance sensitive.

I think there maybe some lurking need to have multiples of
DEPTH, although most of this code is long gone, and losing
"DEPTH" would make much of it more readable.

THREATEXT is also stale code - probably ought to be polished and
included, or dumped.

I'll check the documentation covers these.

AFAIK "+" fail high, "-" fail low, "&" thinking, "." done thinking.
