Merge branch 'mingw/ref-filter-remote-name'

This reflects v2 of the ref-filter-remote-name branch, submitted as:

https://public-inbox.org/git/[email protected]

The only addition is a fourth patch that marks all of this shebang as
experimental, subject to design changes without prior warning.

By exposing this as an experimental feature to users, hopefully this
patch series will mature quicker (not so much in the "beautiful code"
sense, but more in the "does it work in practice" sense).
