The above patch has a typo! Oops. I'd love to see this feature go in when the
sw=0 indent fixes go in, because then we can just "set ts=8 sw=0 sts=-1" and
use tabstop alone to adjust indent width. The second patch (corrected below)
makes it so sw can also be negative (which means it falls back to tabstop) just
for consistency with sts. I'm not sure if it's the right thing to do but it
might be.
