Multiline does not work as expected for some comments

[snuyanzin]

Description

As I understand the issue is present for the queries with one-line comment ending with ; or similar C-style comments For example I want to type a query in multiline mode

select -- this is my query;
2;

or

select /* this is my query; 
 */ 2;

and pgcli does not allow me to continue with the second line, instead it executes only the first line with error in case C-style comment

unterminated /* comment at or near "/* this is my query"
LINE 1: select /* this is my query
               ^
