Feel free to push that, it makes sense.  But maybe halfway at 0.8?

More seriously though, this clashes with Company's overlay-based
dropdown, and I don't know how to fix that.  Company makes Flymake's
end-of-line overlay temporarily invisible, which is good, but
it still takes a lot of space, so the dropdown is ridiculously
offset to the right.
