This information should live below the --- line (in the ""cover letter""
for this single-patch case), as we don't really care about that once it
hits the git history

Agree. The statement below caused some confusion, which is why I added 
it to the commit description.

If one patch depends on another patch in order for a change to be 
complete, that is OK. Simply note “this patch depends on patch X” in 
your patch description.
