This patch adds a ReGroupHelpFormatter class, which regroups positional
arguments in the usage line as discussed before. It builds on the reworked
usage formatter in bugs/python.org/issue11874 (which keeps usage as a list
longer).
For a complicate parser, usage may look like:
usage: regp [-h] foo [arg1 [arg2 [arg3 [arg3 ...] [arg4]]]]
