I thought I did just that, with my rewrite of your line (best if you
view the mail in fixed-width font) :)

Note that qemu.git already has a .exrc file that enables default vi
settings for vim users; I'm not sure if there is a counterpart
.dir-locals.el file to set up emacs settings, but someone probably has
one.  Ultimately, having instructions on how to set up your editor so
that 'TAB' just magically indents to the preferred style seems like a
tip worth having on the wiki page on contributing a patch, but I'm not
sure I'm the one to provide such a patch (since I focus most of my qemu
work on reviewing other's patches, and not writing my own, I don't
really have my own preferred editor set up to indent in a qemu style).
