jwutils.Cmd.add_subcommands() had two issues. First, it failed for more than one command, and with that fixed, it only added the first command of a list of commands passed as an argument. This commit fixes both issues and leaves some logging and cleanup in place, which was used during debugging. Signed-off-by: Jan Lindemann <jan@janware.com>
