cli: enter on empty line
When enter is pressed on empty line in cli it continues with the current line as if it was multiline command. However the correct behavior is to terminate the current line and start a new one.
$ aql2
> [ENTER]
+ [ENTER]
+ [ENTER]
+ [ENTER]
+ [ENTER]
+ print 1 [ENTER]

expected:
