It's about not treating Windows developers as second class citizens.
Their platform uses \r\n as its native line ending format, so they
should be able to work in that format without any hassles by following
some simple instructions (such as "ensure you have version X of the
Windows hg client, enable the win32text extension and configure it in
such-and-such a way"). Not "oh, yeah, that's an issue but if you search
the Intarwebs there are a few different things you can do that kinda
sorta work but are a bit fragile and klunky".

The precise order the two issues (server side enforcement and client
side assistance) are dealt with doesn't really matter because *both*
issues need to be addressed before we migrate.

win32text needs to be usable on non-Windows clients so that tarballs
generated on a *nix machine get the line endings right in the
Windows-only files.
