riched20: ME_SetSelection -1 to -1 behavior fix

[Matt Finnicum]

Mark,
This patch, like the first one you submitted, is linewrapped (meaning
it won't apply cleanly). I'd suggest just attaching the patch to your
e-mail, so you don't have to worry about these things.

Also, it's always nice to have a conformance test for things like
this. Perhaps show that it's the correct behaviour for both
EM_EXSETSEL and EM_SETSEL? If you've got any questions on writing one
(or just want me to do it for you), just send me an e-mail.

Thanks for contributing,
--Matt
