Description
For example we have a Prolog multine, and in many Prolog interpreters the dot ('.') character marks the end of the sentence, so it would be nice to exit from the multiline mode after you typed dot. So there would not be needed to use Meta+Enter to exit multiline.
But with the current interface I wasn't able to find how to do that.
See
some_rule(A, B, C) :-
A > 0,
B < 0.
C. % if we press Enter after typing dot the multiline should end here, and proceed to the REPL execution.

Research direction
Start by tracing the interface's multiline mode and the handling of Meta+Enter before REPL execution. Determine where submitted input can be inspected for a terminating dot, then verify that pressing Enter after the dot exits multiline mode and proceeds to execution without changing other multiline behavior.
