[PATCH 0/3] teach git-checkout -B WAS builtin/checkout: DWIM with -f -b

Right now, the -f/--force in git-checkout doesn't carry over to -b operations - ie. you can't do git checkout -b branch on an existing branch.

This patch allows you to do this with the -B option, so that one can do

  git checkout -B branch ref

which is equivalent to

  git branch -f branch ref && git checkout branch
