Description
When running examples/autocompletion.py, if I attempt to complete an animal starting with 't', the options are 'turkey' and 'turtle'. In this instance, I would expect 'tur' to be filled in before I start tabbing through the options, but instead it cycles immediately to 'turkey', then 'turtle', then back to 't'.
It's unclear to me what the intended behavior of this is. There appears to be code to do this in interface.py (insert_common_part), and it looks like this variable is getting set to True, but the code that does the insertion never seems to get hit.
For reference, I'm using Python 2.7 on Windows 10.

Research direction
Start by reproducing the behavior with examples/autocompletion.py using the reported animal choices, then inspect interface.py and the insert_common_part path. Confirm why the common-prefix insertion is skipped and verify that entering “t” fills “tur” before completion choices cycle.
