trydiff: move check for quietness out of diffline()

By moving the condition out of diffline(), the call site becomes
clearer and diffline() no longer closes on any variables.

Note that this changes the value of the header variable from [''] to
[], but there is no difference in how these two are treated by the
following code. The new value seems more natural anyway.

To run the tests, do:

cd tests/
python run-tests.py
