[PATCH 0/8] {master} revamp the handling of -W

[Akim Demaille]

This series of patches address a few shortcomings about the handling
of warning categories:

- Too much duplication.

- Hairy code.

- Théophile pointed out that supports for -Werror=foo has leaked
  to -r and -f (and -ferror=caret, nonsensical, is accepted).

- Joel pointed out that it would be nice to be able to enable
  -Wempty-rule when %empty is used, except if -Wno-empty-rule is
  set, which requires to tell the difference between a disabled
  warning (-Wno-empty-rule), and a warning that was not enabled.

I'd be happy to hear comments.  I shall apply these in a couple
of days.  Then I'll proceed on %empty.


Akim Demaille (8):
  options: no longer document warnings when diagnosing an invalid -W
  diagnostics: no longer pretty-print rules in error messages, carets
    suffice
  diagnostics: factor the list of warning names
  options: don't accept "error=" for -f and -r
  options: simplify the handling of -W
  diagnostics: revamp the handling of -Werror
  style: more argument handling of -W into the diagnostics module
  getargs: minor simplification
