Oops, it's Stable 1.0.

Yes, that sentence technically covers it, but I find the paragraph
confusing all the same.  Two ways to get my R-by:

1. Split the patch in two: part 1 is the get_maintainer.pl modification,
   part 2 is the MAINTAINERS update.  Each part does just one thing
   then, which allows simple commit messages.  That's what I'd do.

2. Keep the patch as is, but improve the commit message.  Here's my try:

    MAINTAINERS: Fall back to git unless we have a human, add qemu-devel@

    From: Stephen Warren <swarren@wwwdotorg.org>

    Add an entry to MAINTAINERS that matches every patch, and requests the
    user send patches to qemu-devel@nongnu.org.

    It's not 100% obvious to project newcomers that all patches should
    be sent there; get_maintainer.pl doesn't say so, and since it
    mentions other lists to CC, the wording "the list" from the
    SubmitAPatch wiki page can be taken to mean only those lists, not
    the main list too.

    The F: entries were taken from a similar entry in the Linux kernel.

    On its own, this would break fallback to git, because now every file
    has a maintainer of sorts.  Modify get_maintainer.pl so that mailing
    lists (L: lines) no longer prevent the fallback, only humans (M:
    entries).  This portion of the patch was suggested by
    pbonzini@redhat.com.

    Several pre-existing entries have a list but no human.  These now
    fall back to git.  That's a feature.

In addition, consider changing the "All patches CC here" line to "All
patches must be sent to this mailing list".
