From: Torsten Bögershausen <tboegi@xxxxxx>
git blame reports lines as not "Not Committed Yet" when they have
CRLF in the index, CRLF in the worktree and e.g. core.autocrlf is true.
Since commit c48053 "new safer autocrlf handling", files that have CRLF
in the index are not normalized at commit when e.g. core.autocrl is set.
Whenever a CLRF conversion is needed (or any filter us set), load the
index temporally, before calling convert_to_git()
