Send only the actual error to Console.Error

[ohadschn]

Currently all generated help text is sent to stderr (Console.Error) when an error occurs:

commandline/src/CommandLine/Parser.cs

Line 199 in 7aa501d

.Do((_, writer) => writer.Write(HelpText.AutoBuild(parserResult, maxDisplayWidth)))

Wouldn't it make more sense to only send the actual error there, and send the rest of the help text (both before and after) to stdout (Console.Out)?

Certainly would. +1 vote on that.

According to the GNU coding standards the --help option is supposed to print to stdout, not stderr, so it's already a bug that CommandLineParser is sending help output to stderr.
