* The options were ignored and did not cause any change in behavior, but it did lead to some confusion. Invalid options will now generate an error.
* Removed erroneous --no-config option in help test module.
* Changed the --no-fork test option to --fork with negation to match all other boolean parameters.
Controls whether console log messages are sent to stderr or stdout. By default this is set to warn which represents a change in behavior from previous versions, even though it may be more intuitive. Setting log-level-stderr=off will preserve the old behavior.
Suggested by Sascha Biberhofer.
* pgBackRest version number included in command start INFO log output.
* Process ID logged for local process start/stop INFO log output.
