matplot

[Ben Bolker]

   matplot doesn't seem to pass through options like lwd, cex, etc.
quite the way I'd like.  I've thought of two ways to fix this, I don't
know which is better.

  The first is to treat lwd, cex, etc., exactly like the other options
(col, lty ...) --  (these diffs are long, skip down two pages if you want
to see the other way)

! 	                  cex=cex[i])
  	}
  }


  The second is to pass extra options through ... -- I don't know if this
breaks anything, it doesn't seem to for me (and it may be more general).
