Remote renderContent() method bugs

From Bob McWhirter:

Using the xml-rpc, renderContent() sometimes seems to forget some <p> tags
around <a> tags.

Compare the PREVAYLER space via docs.codehaus.org, and the magical XML-RPC
stuff I'm doing served by http://bong.codehaus.org/ (just a testsite), which
doesn't layout quite as nicely.

Also, it seems some security checks are going wonky, so that if I render a
page from a non-public space, the links don't link, even though I'm login()'d
as a use who can read the pages.

Also, the docs for renderContent() don't mention the spacekey param.
