--- Comment #4 from Vladimir Panteleev <dlang-bugzilla at thecybershadow.net> ---
This is a regression.

Simplified test case:

/////////////// test.d ///////////////
void main()
{
    import std.getopt;

    string[] args = ["program", "-h"];
    getopt(args, config.passThrough);
    assert(args == ["program", "-h"]);
}

What if I want to generate my own help screen? E.g. if I'm using a library
around std.getopt that generates its own enhanced help screen (e.g.
ae.utils.funopt).
