[R] How to disable using "enter" key to exit the browser in debugging mode

[Prof Brian Ripley]

You do not mean the "enter" key: it is not that which exits the 
browser but rather a newline (which can be entered via 'return', and 
in other ways).

This is part of the parser, and there is no way to turn it off.

Somehow other experienced R users have never encountered this.  But if 
you wish you could submit this as a 'wishlist' request to R-bugs, and 
if enough users support it (and especially if someone submits a 
high-quality patch to do this), it might be added in a future release.
