Applied, thanks.

I made a few changes:

  o require_cmd dot to output error when user does not have dotty
  o use TMPDIR for temporary files (falls back to /tmp when unset)
  o work with untitled buffers (the generated temporary filename was  
wrong)
  o escape HTML in potential errors

A minor problem is that with no input dot does not give an error. One  
could test the date of the generated PDF, but probably not worth it.
