[REBOL] Newlines

Newlines
Hello Anton and Joel,
Thanks for the help. The code below works perfectly on the pages I've tested, though
it takes a second or two on long pages. It strips all the html and newlines and extraneous
whitepsace.
Joel was right about my original problem. I had a space between two newlines, so now
I'm removing those too.
I hope this gets through. The last two emails I've sent came back as undeliverable. I'm
sending this one via Rebol instead of Netscape.
