add standard vi formatting directives to all source files?

[Robert P. J. Day]

  i notice that some, but not all, BB source files end with the
editing directives:


/*
Local Variables:
c-file-style: "linux"
c-basic-offset: 4
tab-width: 4
End:
*/


  if this is the consensus, i can toss together a patch that adds that
to all files that currently don't have it and send it offline to rob.
are there any objections?  is that content agreeable to everyone?
