Change default author substitution to avoid updating test hashes.
Rather than '%s <%s%s>', just use '%s%s'. The two should be
functionally equivalent. All tests pass.
Added a comment about the handling of missing authors. This is tested
by test_push_to_default in tests/test_push_command.py; it is treated
the same as before.
