Assume I format the patch series:

  http://lists.nongnu.org/archive/html/qemu-devel/2015-06/msg06677.html

into a single file, with

  git format-patch --notes --cover-letter --numbered --stdout

and then run scripts/get_maintainer.pl on the resultant patch series file.

Before this patch, I get:

  Paolo Bonzini <address@hidden> (maintainer:X86)
  Richard Henderson <address@hidden> (maintainer:X86)
  Eduardo Habkost <address@hidden> (maintainer:X86)
  "Michael S. Tsirkin" <address@hidden> (supporter:PC)

Since Michael was listed at the bottom of that list, I didn't CC him. (I
wanted to give him a breather after my many PXB iterations.)

Turns out that wasn't a good choice. With this patch for MAINTAINERS in
place, the script reports Michael at the top:

  "Michael S. Tsirkin" <address@hidden> (supporter:PC)
  Paolo Bonzini <address@hidden> (maintainer:X86)
  Richard Henderson <address@hidden> (maintainer:X86)
  Eduardo Habkost <address@hidden> (maintainer:X86)

Maybe I should have considered something else than just the ordering of
the names in the list, not sure...

Hm, yes, this is at least partly (if not fully) my fault. MAINTAINERS says

        S: Status, one of the following:
           Supported:   Someone is actually paid to look after this.
           Maintained:  Someone actually looks after it.

I didn't realize this distinction, and I also didn't realize that
"supporter" and "maintainer" were derived directly from "Supported" and
"Maintained".

It would be helpful if developers with more jurisdiction (according to
the Supported / Maintained / Odd Fixes classification) were listed
higher in the output.

Thanks
