Parse failing on otherwise valid arguments

[Qix-]

	auto compress = (
		command("compress").set(sc, subcommand::COMPRESS)
		| command("decompress").set(sc, subcommand::DECOMPRESS)
	) % "(de)compress stdin to stdout";

	auto convert = (
		command("convert").set(sc, subcommand::CONVERT),
		value("input.vox", in_path),
		value("output.tox", out_path)
	) % "convert a .VOX scene to .TOX asset";

	auto info = (
		command("info").set(sc, subcommand::INFO),
		value("input.tox", in_path)
	) % "show information about a .TOX asset";

	auto verbose_flag = option("-v", "--verbose").set(verbose, true)
		% "enable verbose output";
	auto help_flag = option("--help").set(help, true)
		% "show this help message";

	auto cli = one_of(
		(
			verbose_flag,
			one_of(
				compress,
				convert,
				info
			)
		),
		help_flag
	);

With the above, I get the following manpage output (looks 100% correct):

SYNOPSIS
        tox [-v] (compress|decompress)
        tox [-v] convert <input.vox> <output.tox>
        tox [-v] info <input.tox>
        tox --help

OPTIONS
        -v, --verbose
                    enable verbose output

        compress|decompress
                    (de)compress stdin to stdout

        convert <input.vox> <output.tox>
                    convert a .VOX scene to .TOX asset

        info <input.tox>
                    show information about a .TOX asset

        --help      show this help message

However, only compress and decompress work; convert and info cause clipp to fail at the parsing step.

Seems like a bug - is that the case? Or is there some sort of workaround for this?

Workaround is to split out the compress and decompress commands into two separate values and include them at the top level one_of group instead of nested group.

Still wish the way I have it above would work, though.
