The problem is that setting the Rd-mode, and activating font-lock
doesn't actually fontify the buffer. This should be unrelated to whether the
buffer visits a file or not, *R* buffer also doesn't  visit any file.

If I manually call font-lock-fontify-buffer, the *RoxyPreview* buffer is
fortified. If I call it from Rd-mode and ess-roxy-preview-Rd functions,
it is not. I must be missing something here.
