[PATCH 0/3] Improve POSIX compatibility and general portablity

git-subtree is considered to be a Bash only script and not POSIX compatibile.

I removed the /bin/bash and tested with dash. All the tests passed.

I also followed some of the advice found in https://wiki.ubuntu.com/DashAsBinSh for converting a bash script to be more portable.

Paul Campbell (3):
  contrib/subtree: stop explicitly using a bash shell
  contrib/subtree: remove use of -a/-o in [ commands
  contrib/subtree: replace echo options with printf
