The following patch fixes it (based on

pyrepl/pyrepl/historical_reader.py

Lines 301 to 303 in b55cc6d

	def test():
	from pyrepl.unix_console import UnixConsole
	reader = HistoricalReader(UnixConsole())

But then using e.g. Up crashes:

Not sure how useful (the test/__main__ in) completing_reader.py is in the end though..
