unknown b0f899e977 Bug#28779 (mysql_query() allows execution of statements with unbalanced
comments)

Before this fix, the server would accept queries that contained comments,
even when the comments were not properly closed with a '*' '/' marker.

For example,
  select 1 /* + 2 <EOF>
would be accepted as
  select 1 /* + 2 */ <EOF>
and executed as
  select 1

With this fix, the server now rejects queries with unclosed comments
as syntax errors.
Both regular comments ('/' '*') and special comments ('/' '*' '!') must be
closed with '*' '/' to be parsed correctly.


mysql-test/r/comments.result:
  Unbalanced comments are a syntax error.
mysql-test/t/comments.test:
  Unbalanced comments are a syntax error.
sql/sql_lex.cc:
  Unbalanced comments are a syntax error.
