This line is too long, normally we allow long line for logs, but the
intention there is to enable user to search a log message in the code;
when line is broken search fails.
But when there is a format specifier in the log, it already break the
search and there is no point to keep the string in single line, which
reduces code readability.

I will break the line while merging.
