Description
move of pytest-dev/pytest#532
pytest -f appears to latch to the set of test cases on first run and does not detect when new test is added.
e.g. test_foo.py:
def test foo(): assert 0
run pytest -f test_foo.py
(one test failing)
edit test_foo.py, add
def test_bar(): assert 0
(still only one test failing)

Research direction
Reproduce the behavior with the test_foo.py example and pytest -f, first confirming that the initial run reports one failing test and the added test is ignored. Trace the loop-on-failures handling for this command, then add coverage showing that test_bar is detected and reported on a subsequent iteration.
