For version 3, we want the args section to immediately follow the usage section in the default help message. One change that I am unhappy with is needing to make "write_arg" in app/help.rs accept an extra param that makes it suppress the extra line. This is to prevent an extra blank line from appearing between args and options in the default help, and seems necessary, but there might be a better way.
