Okay, a revised proposal:

- recognize both -W and -Wextra
- for --help output and in the manual, only describe -Wextra
- document all the little extra things that -W[extra] currently does

i.e., print no deprecation warnings for -W, leave it in there, but don't
advertise it anymore.  It's too confusing.

I can do the above, no problem.  Right now I do not have the time to split
out -Wextra into 20 separate options, or to split out extra_warnings into
20 separate variables.  However, the updates to the manual should help
anyone who wants to do so.
