Changes (by simonpj):

  * milestone:  6.6.2 => 6.8 branch

Comment:

 Good point.  Although it's specifically legal to name a file on the
 command line that contains a module with a different name.

 Proposal:
  * Cut down error message to display a minimal cycle
  * Display file names where not same as module name
  * Omit the "main:" stuff
