CommandLine: Exit successfully for -version and -help

Browse Source 
Tools that use the CommandLine library currently exit with an error
when invoked with -version or -help. This is unusual and non-standard,
so we'll fix them to exit successfully instead.

I don't expect that anyone relies on the current behaviour, so this
should be a fairly safe change.
