[PATCH 0/4] contrib/subtree: general updates

Less ambitious patch series this time.

James and Michael's patches add if clauses that use the bashism 'if []' rather than 'if test'. I've left them as they are to match the other if clauses within the git-subtree.sh file. I remember reading a comment on the list about matching the local style being more important than the overall project's style. I'm happy to change them otherwise.

James Roper (1):
  contrib/subtree: Teach push to use --force option

Matt Hoffman (1):
  contrib/subtree: Replace invisible carriage return with a visible \r

Michael Hart (1):
  contrib/subtree: Teach push to abort if split fails

Paul Cartwright (1):
  contrib/subtree: Fix typo (s/incldued/included/)
