"we"? I always use capital letters here; so does Michael Niedermayer
(mostly). In the last two years, 4679 patches used a capital letter
after the ':', whereas 4409 used a non-capital letter. Granted, 3286 of
the 4679 are from me, but I don't think we have a policy here. Neither
should we.

And I thought I wrote it in that way.
