Whenever suggestion for this lint does not fit in one line, lint will generate two help messages. The second help message will always contain the suggestion. The first help message refers to suggestion message, and it should adapt depending on the location of the suggestion: - inline suggestion within the error/warning message - suggestion separated into second help text
