1) eol native
2) Require $Rev:$
3) Require svn:keywords="eol-native, Rev"
All java and xml files automatically get native eol-style if you use
the subversion/config file in svn.
Okay, we now require the svn:keywords to be set to Rev
and svn:eol-style to be set to native
We don't require $Rev: $ in the code, because that is much harder to do.
The pre-commit checks ended up not working, reopen the bug.
This hasn't been a problem in practice, so I am closing this now. If
we decide we _really_ want these checks in the future, we can
re-evaluate adding them.
