- Rename PW_ARG_COUNT to PW_MACRO_ARG_COUNT.
- Reorganize the arguments.h header to put the high-level, easier-to-use
macros first (PW_DELEGATE_BY_ARG_COUNT and PW_COMMA_ARGS).
- Fix the test that demonstrates what happens when PW_COMMA_ARGS is
used incorrectly.
- Update the documentation for arguments.h.
