bug#21305: 25.0.50; `get-buffer-window-list' doc - what order?

[Drew Adams <drew.adams@oracle.com>]

The doc string says: "Windows are scanned starting with the selected
window."  What does that mean?  Scanned?  How so?  In what order are
they scanned (besides starting with selected)?  And how is the scanning
used?

What I would really like to know should have little or nothing to do
with "scanning".  It is what order the list is in.  Details of how the
function computes the list are not so important, but if you have to tell
us that in order to specify the resulting order, so be it.

Please update both the doc string and (elisp) `Buffers and Windows'
to tell us what order the list is in.
