For each warning found in the log, _log_check_warn() would output a
line stating that it had found a warning, then the actual warning and
finally an empty line. This is quite excessive when there are many
warnings in the log.
With this change the output is instead a line stating how many
warnings were found, followed by the warnings. This makes the output
much more compact and actually much more readable.
