OK, so it's a bug in pico, or better misunderstanding between pico and
Miniwin (->TosWin).

none. The problem is here: Miniwin supports "insert mode". It can be
turned on and off (by an ESC seq). Then there's ESC code for "put just
one char in insert mode". Miniwin counts on that every program first
turns on insert mode, then puts the characters to the screen and at last
turns the insert mode off. Pico, most probably, does it in a different
way - first it detects the posibility of insert mode by locating the
"insert mode" ESC code, and then uses just the "put 1 char in ins mode",
which is NOT supported by Miniwin.

The simplest solution is to disable the "insert mode" support, which was
done by the patch to termcap found in my previous mail. Correct solution
is to implement the "put 1 char in ins mode" which pico uses.
