Hmmmm, can I suggest something here? I can't remember of the top of my head if JBoss CLI works like this, and I'm not that the above statement matches my suggestion:

One thing I love of tab completion in zsh (as opposed to bash) is the following: Imagine that as you say you have both 'file' and 'file2'

The first time I do: f + tab, it will show: file

But if I click tab again, so: f + tab + tab, it will give me: file2

If there was a file3, doing: f + tab + tab + tab will give me: file3

…etc

IIRC, with bash, you had to actually	type 2 to be to get to file2.

Does people find zsh style tab completion more useful too?
