[Windows] [lem-pdcurses] winpty problem

[Hamayama]

I found the problem of lem-pdcurses on Windows.
(escape key combination becomes not to work)

This is caused by winpty.

When the cursor position (lines, cols) [1-based] is in the range of (1, 2) to (1, 8) and
you input escape key, escape key combination (such as Escape-<) becomes not to work.

Workaround is not to input escape key in this range ...
