* The --warnings=failed-read option
This new warning control option suppresses warning messages about
unreadable files and directories. It has effect only if used together
with the --ignore-failed-read option.
* The --warnings=none option now suppresses all warnings
This includes warnings about unreadable files produced when
--ignore-failed-read is in effect. To output these, use
--warnings=none --warnings=no-failed-read.
