tbh, if it were better about about not adding people to CC list just
because they had some commits around the effected code, I think that
would be better.  Better populating of REVIEWERS and higher weight to
REVIEWERS over git-blame would help, I think.  (It would be nice if it
wasn't a perl script, or at least that would make it easier for me to
fix that..)

As far as being CC'd on part of a patchset vs whole patchset, I'm not
really sure how to do that w/ git's cc-cmd.  I admit it would be nice
if it at least CC'd everyone on the cover letter for context, although
for a patchset that touched a lot of areas I think I'd prefer just to
be CC'd on cover letter plus individual patches.  I guess if there was
a way for letting get_reviewers script see the whole patchset upfront,
then inventing a way to get individual preferences about being cc'd on
whole patchset vs cover letters and individual patches would be an
option.

I do still like the general concept, to make it easier for the right
people to be CC'd on a patch, especially for drive-by submitters.

> -Notes:
> -  Using "-f directory" may give unexpected results:
> -      Used with "--git", git signators for _all_ files in and below
> -          directory are examined as git recurses directories.
> -          Any specified X: (exclude) pattern matches are _not_ ignored.
> -      Used with "--nogit", directory is used as a pattern match,
> -          no individual file within the directory or subdirectory
> -          is matched.
> -      Used with "--git-blame", does not iterate all files in directory
> -  Using "--git-blame" is slow and may add old committers and authors
> -      that are no longer active maintainers to the output.
> -  Using "--roles" or "--rolestats" with git send-email --cc-cmd or any
> -      other automated tools that expect only ["name"] <email address>
> -      may not work because of additional output after <email address>.
> -  Using "--rolestats" and "--git-blame" shows the #/total=% commits,
> -      not the percentage of the entire file authored.  # of commits is
> -      not a good measure of amount of code authored.  1 major commit may
> -      contain a thousand lines, 5 trivial commits may modify a single line.
> -  If git is not installed, but mercurial (hg) is installed and an .hg
> -      repository exists, the following options apply to mercurial:
> -          --git,
> -          --git-min-signatures, --git-max-maintainers, --git-min-percent, and
> -          --git-blame
> -      Use --hg-since not --git-since to control date selection
