Thanks for pointing that out.
I'll make the same change to system_exec()
that I made to system(), so it won't try to
initialize ncurses.

Also, on Linux/FreeBSD, system_exec() calls the
C system() routine, so I/O redirection is possible,
but redirection in system_exec doesn't work on DOS/Windows.
I'll add a note to the docs.
