inserts extra line breaks when it contains http://

I believe this wasn’t happening before. Basically, if I do this while composing:

http://oi41.tinypic.com/x5csx.jpg

this is what I see in the preview:

http://oi42.tinypic.com/abjngg.jpg

I’ve done a few tests and it seems that the problem is the http:// part. If I change that to htttp:// (three t’s), or use http:|| (pipes instead of bars), or any other change that make http:// disappear, the preview displays correctly.
