tab completion FC 21

[Stephen Davies]

I have just upgraded a box from fc20 to fc21 using fedup and tab completion 
has gone bezerk.

I have erased the bash-completion package but the weird behaviour continues.
It is even guessing/remembering passwords.

In most cases, hitting tab during command entry does nothing. In others 
(randomly so far as I can see) it pops up a list of words (including spelling 
errors).

Even worse is when I try to type a path eg /usr/local/bin/foo, it puts spaces 
between each component and I have to backspace to remove them.

How can I really get rid of this rubbish and return to the good old, simple 
completion?

Cheers and thanks,
Stephen
