How to configure for bash-style partial completion?

[MartinSGill]

I'm trying to figure out how/if it's possible to configure PSReadline for the way default bash seems to handle completions.

Current behaviour is that when I press to complete it inserts the first item found at the prompt (e.g. the first file in the directory). I've tried setting tab to MenuComplete, but all that does is present options, it doesn't fill the prompt with as much as it can.

What I want is for it to insert as much common text as it can and then presenting options.

e.g. if I have

ProjectA.SomeThing
ProjectA.SomeOtherThing
ProjectB.SomeOtherThing

• > Pr<tab> --> > Project|
• > ProjectA<tab> --> > ProjectA.Some|

What combination of settings do I need for this behaviour?
