  1. Fix rebar_utils:expand_env_variable/3 

    The function may fail with a badarg exception because the first regex returns
an iolist() which is allowed to be a improper list. In this case '++' cannot
append to the iolist. The correct way to append something to an iolist() is

  [iolist(), "tail"]

because iolist's are allowed to be arbitrarily deep lists.
