bug#16854: 24.3.50; ert-run-tests-interactively t selector not working

[Helmut Eller]

When I run this 

(require 'ert)
(ert-deftest infloop0 () (while t))

with: emacs -Q -nw -l infloops.el -f ert

Emacs starts up and asks: "Run tests (default t): "
If I enter: "t RET"
then ERT does not run anything and simply writes:
"Ran 0 tests, 0 results were as expected"

The expected result is that all tests should be executed.
