[R] browser always enters debug mode

[Paul Murtaugh]

It appears to be a difference between versions 2.* and 3.* in the way 
that a newline ('enter') is handled at the browser prompt. Formerly, it 
would continue execution of the function; now it kicks you into 
debugging mode.  To get the old behavior, you need to enter 'c' at the 
browser prompt.
