Exit command and semicolon with multiline client option

[ilyas-pro]

ClickHouse client version 1.1.54327

If you type any space symbols before semicolon and after exit command, there is syntax error occurs.

examples:

:) exit ;
Syntax error: failed at position 1:

:) exit
:-] ;
Syntax error: failed at position 1 (line 1, col 1):

This behavior is inconvenient when you in multiline mode. If you type exit command and forgot about semicolon, you can not complete your command without syntax error message.
