Please pardon that everything that follows is griping.

I'm not having much luck with this.  The doc should mention that window
zero is automatically created as the whole terminal.  Also there's no
check that the targetwin argument is really an integer; I typo'd a "q"
for a "1", got some errors about the window already existing (apparently
because non-integers are read as "0"), and ended up with a core dump:

(gdb) where

(etc.)

The doc for "zcurses -m" says "moves targetwin to new coordinates" but
really it positions the cursor within the target window, doesn't it?
Maybe better phrasing is all that's needed.

Also I none of the strings I send with "zcurses -s" show up in the
window.  A border added with "zcurses -b" will display, but that's all.
"zcurses -c" has a similar problem.
