Committers guide: wordsmith the section on maintainers

- remove an aside about reading the mailing list. This is taken care of
  by the later sentence about reading revision history
- use a slightly stronger admonition ("important" instead of "note") for
  the comments about not sending mail directly to the maintainer.
- Refer explicitly to the 'MAINTAINERS' file at the root of the tree
- Use the language of "asking for a review" instead of "sending the
  change to them" which, again, encourages a more public interaction.
- Remove the weasel language "it may help" and just encourage people to
  scan the history
