LEWG, SG16,

CC: Billy, Corentin

Please find attached draft 2 of proposed normative wording for D1030R4
std::filesystem::path_view. Changes since draft 1:

- The reference implementation has been upgraded to match this proposed
wording, and has been found to work well.

- For all existing path consuming overloads, no longer remove the
existing overloads, instead add weakly selected path view overloads.

- Path view components now default to not interpreting path separators.

My thanks in advance to anyone willing to review this draft before it
gets formally submitted for LEWG to review next mailing. Please don't do
a deep dive on the normative wording yet though, as LEWG needs to sign
off on this design first.
