Description

In sqlline, a single semicolon (or space(s) followed by semicolon) - "[ ];*" - produce an error

;
Error: PARSE ERROR: Encountered "<EOF>" at line 0, column 0.

It's not necessary a real bug, but I think it can produce "too much" error for nothing.

Don't need/want an error for an empty command.
