[R-SIG-Mac] Bug in data editor

[Duncan Murdoch]

The bug

https://bugs.r-project.org/bugzilla3/show_bug.cgi?id=15463

appears to be R.app specific.  All of the data editors (R.app, X11, 
Windows) round the data for display, but the one in R.app appears to 
reload the data from the rounded values, whether edited or not.

I've just confirmed this still exists with the 3.0.2 release:

R version 3.0.2 (2013-09-25)
