I don't think the "Documentation:" line helps much here, though.  It's
just an awkward first line.

We've previously discussed rearranging the function/variable output in a
more "readerly" way -- for instance, it's odd that the block of indented
things come before the doc string, because those indented things aren't
what's most vital for normal users to know.

But even if the buffer started with:

  resize-mini-windows is a variable defined in ‘C source code’.

  How to resize mini-windows (the minibuffer and the echo area).
  A value of nil means don’t automatically resize mini-windows.

It'd still be an awkward doc string, because it's just an awkward
semi-sentence.
