(Guile-SDL) Documentation buglet

[Luca Saiu]

Hello.

While playing with Guile-SDL with a friend I noticed a buglet in the
"Quick Start" example from the manual.  SDL_KEYDOWN in the main loop
should be key-down instead.
I guess SDL_KEYDOWN was used in some older version, and the manual
didn't get updated.

Speaking of the first example, I would also add a guile invocation
example; it's nice to have it, just once near the beginning.  If the
demo program has been saved as /tmp/demo.scm and the installation prefix
is /usr/local the thing should be

$ guile -L /usr/local/share/guile/site /tmp/demo.scm
.

Thanks for working on this handy binding library.  It's very fun to use.
Regards,
