help: mark boolean flags with [no-] to explain that they can be negated

That is, help gets tweaked thus:

  global options ([+] can be repeated):
   -v --[no-]verbose      enable additional output


Other proposals have included:

  global options ([+] can be repeated, options marked [?] are boolean flags):
   -v --verbose[?]        enable additional output

and

  global options ([+] can be repeated, options marked [^] are boolean flags):
   -v --verbose[^]        enable additional output

which avoid the unfortunate visual noise in this patch. In this
version's favor, it's consistent with what I'm used to seeing in man
pages and similar documentation venues.
