    >>> Is this a bug - If there is a break in the title of a plot ( with
    >>> \n), the symbols or math is "broken"?  for example:

   >> > version
   >> ....
   >> major      0
   >> minor      64.1
   >> ....
   >> > plot(0)
   >> #This works just fine
   >> > title(expression(paste("This works with math ", mu)))
   >> #This "looks" bad
   >> > plot(0)
   >> > title(expression(paste("This does not works with math \n", mu, "with this additional text")))

Excuse me, Partha, I misinterpreted your question/ statements
(and we *did* fix a bug here!) -- I'm feeling silly, really sorry...

but there *is* still a bug here  :

 The line break happens alright, but the two lines are not centered
 properly, but rather "as a whole"

 This is shown (somewhat more easily for cut&paste)

  plot(0);title(expression(paste("Bad\n",mu," with much much more text")))

--> I send a bug report to R-bugs (unless there's one already there)
