If what you want is a line, or switch in your configuration file, fine. But I
would think in general that it would not be easy to implement. And I certainly
use the ability to type a line with a return in them. And the GAP input
routine would need to be rewritten to figure out when a line was complete. For
example
x := 4+ 4
+3;
would probably not give you what you want.
