[PATCH 0/3] commit-tree updates

Here are a handful of patches to the lowest level plumbing commit-tree to teach it to record extended headers. With this series, scripted Porcelain like rebase--am can propagate the "mergetag" header while rebasing.

Junio C Hamano (3):
  commit-tree: update the command line parsing
  commit-tree: teach -m/-F options to read logs from elsewhere
  commit-tree: teach -x <extra>
