  - https://github.com/dustinkirkland/byobu/pull/15
  - Fixing BYOBU_TEST issues
  - The first issue was that command -v, which and type were always
    returning an error code when executed without an extra argument.
    so BYOBU_TEST was always falling to which because it was the last one.
  - The second issue was, command -v didn't work because of a different
    reason. When executed in a shell (at least my shell) using variable
    substitution, the shell was trying to find a binary called
    "command -v" so it was failing.
