eol: fix missing trailing newlines in comitted files

Some text editors (Eclipse, for example) do not add trailing newlines,
so diffs often contain annoying "\ No newline at the end of file".
This patch to eol extension simply adds trailing newline on commit.

basic test for hg debugrebuildstate

  $ hg init repo
  $ cd repo

  $ touch foo bar
  $ hg ci -Am 'add foo bar'
  adding bar
  adding foo

  $ touch baz
  $ hg add baz
  $ hg rm bar

  $ hg debugrebuildstate

state dump after

  $ hg debugstate --nodates | sort
  n 666         -1 bar
  n 666         -1 foo

status

  $ hg st -A
  ! bar
  ? baz
  C foo
