When I invoke lynx the say way the code does, lynx goes into full-screen
mode. It isn't writing to stdout via the shell's redirect, it' using
ncurses to manipulate my screen.
When I invoke lynx without the shell, it writes to stdout as expected.
Lynx isn't a shell script, you can invoke it directly in the exec() call.

No matter what we think of Linux versus FreeBSD, etc., the one thing I
really like about Linux is that it has Microsoft worried. Anything
that kicks a monopoly in the pants has got to be good for something.
