The computations done by print.survfit are now a part of the results returned by 
summary.survfit.  See  'table' in the output list of ?summary.survfit.  Both 
call an internal survmean() function to ensure that any future updates stay in 
synchrony.

This was a perennial (and justified) complaint with print.survfit.  Per the 
standard print(x) always returns x, so there was no way to get the results of 
the print as an S object.
