Fix window I/O

This fixes cursor positioning in PDCurses. It also fixes an issue
where the first received character was rendered as a space. The
wrefresh() call is now unneeded since wgetch() does a refresh.

VT52ish Building Running Motivation

README.md

 VT52ish

This is a pretty inaccurate emulator of a VT52. I'm sure it's missing
several features. I mostly wanted to make TUI programs work using
TERM=vt52. I got my information about VT52s from the terminfo
database, Wikipedia, and this page. The emulator runs inside another
terminal emulator using (N)Curses.

 Building

This project requires a Curses library, a C99 compiler, and a POSIX
environment. I couldn't make it completely POSIX-compliant due to a
few necessary tty ioctls, but it probably works on many Unices. If
you have the right environment, you can build it with make. The
executable is called vt52ish.

 Running

To run an interactive Bash shell, something like this will work:

./vt52ish env PS1='$ ' bash --norc --noprofile

You can nest the emulator an arbitrary number of times:

./vt52ish ./vt52ish ./vt52ish env PS1='$ ' bash --norc --noprofile

Most simple ncurses programs that don't require colors will probably
work to some extent in this terminal.

 Motivation

I wanted to make this mostly to try implementing a terminal emulator.
I decided to emulate the VT52 because of the simplicity of its
protocol.
