This is an issue when there is more than one possible completion.  I will
assume that you mean that when you say you want "completion" on the first
TAB, you want the longest common prefix displayed, then subsequent TABs to
cycle through the possible completions as menu-complete usually behaves.

If this is the behavior you want, bind TAB to menu-complete and set the
readline variable `menu-complete-display-prefix'.
