How do I undo the 3 character limit before auto complete pops up?

[Reaper176]

I have several sets of autocomplete csv's that I would like to start showing suggestions on the first letter. This was not a problem until recently. Anyone know what I would need to change for this to go back to the way it was. Please and thank you.

I tried:
Changing:

if not name.startswith("<") and len(name.rstrip()) > 2:

back to

if not name.startswith("<") and len(name) > 2:

This did not look to have any effect.

It was always 3 characters. The only thing that changed was whether space is included when counting characters or not.

If you want to change it to 2 characters change the > 2 to a > 1

It introduces a noticeable delay for bigger tag collections because too many things are matched.
