So, I've been not-working on this, which I feel bad about. Suffice it
to say the day job has required more of my time then usual for the
past few weeks. I want to get back into it, so let's start by
re-raising this issue, which Mark Hammond conveniently summarized

This was and still is a good idea. It would be very nice if you could
un-bitrot it and submit it for inclusion into crew-stable (so that it
may land in the next release, which would hopefully be a somewhat near

I'm thinking that it should take stuff from .hgeols or whatever and
apply rules from .hg/hgrc after that, so both may be used (and for
backwards compatibility), but it sounds like a good idea in principle.

I don't think that is necessary, I will elaborate below.

You seem to advocate a two-step approach: enforce line endings through
win32text, catch any errors that slipped through in a hook (commit
hook is an optional first line of defense, changegroup hooks on the
server to protect the rest of the world).
I think inverting that approach would be better: have strict hooks on
the server to prevent people from pushing inappropriate EOLs, and
provide help on configuring win32text as an extra help for developers
on Windows who use editors that work better with \r\n. That leaves
people to pick their own weapon of choice against propagation of \r\n
(e.g. better editor, commit hooks, whatever) while still making sure
no inappropriate line endings land in the python.org repositories. It
also seems to fit well with the whole consenting adults thing (but
that might just be me).

Taking up the 'none' filter, first, and .hgeols, secondly, in the
win32text extension would be wonderfully helpful, since I don't do
much development on Windows and am therefore not that familiar with
the extension in the first place.
