Make earlygetopt return a list of all option values, use the last value. This fixes: "hg -R" showing a useful error instead of traceback "hg -R foo --repository bar" using bar instead of foo And provides a way for other users of earlygetopt to accept more than one value.

To run the tests, do:

cd tests/
python run-tests.py
