elixir test failure with different version number

gistfile1.txt

PROBLEM:  Changing the version number makes a bunch of tests fail

SOLUTION:  Avoid adding a newline to the VERSION file.  Edit with `vim -b VERSION`.

Try these:\n\n    h(Enum)\n    h(Enum.reverse/1)\n\nTo discover all available functions for a module, type the module name\nfollowed by a dot, then press tab to trigger autocomplete. For example:\n\n    Enum.\n\nTo learn more about IEx as a whole, just type `h(IEx)`."
