Hi Brooks,
I do not think that this is a bug, although it is possibly a documentation
issue. The --help=<> option restricts the output to a specified subset of the
full output obtained with just the --help option. Thus it makes sense that if
both --help and --help=<> are specified on the same command line and that it is
documentated that --help=<> options combine, then the output should be the
entire --help output.
So, how do you feel about this patch ?
Cheers
Nick
