Test in repo using eol extension, while keeping an eye on how filters are
applied:

  $ cd repo

  $ hg up -q -c -r null
  $ cat > .hg/hgrc <<EOF
  > [extensions]
  > eol =
  > EOF

Update to revision 0 which has no .hgeol . Unfortunately, it uses the filter
from tip ... which evidently is wrong:

Abort the merge with up -C to revision 0 ... but notice how .hgeol changes are
not detected correctly: f is filtered with tolf even though there is no filter
for f in revision 0, and it thus ends up with working directory changes.
