bq. How can I provide test cases for this patch?
You can add the reproducer you provided to escape_comments.q and generate an
updated escape_comments.q.out. You can find more details at [Wiki

> when column comment contain \t
> eg: CREATE TABLE `zhangmang_test`(`name` string COMMENT
> 'name{color:#ff0000}\t{color}zm');
> then execute : {color:#ff0000}desc zhangmang_test {color}
> {color:#ff0000}{color:#333333}return :{color} name string
> name{color}
> because \t is the separator, so we should translate it
