complete.el extends the meaning of the variable so that a non-nil non-t
value means "show the help but only on the second attempt to complete".
I.e. if TAB finds nothing to complete, the first TAB will just say "[Next
char not unique]" without bringing up the *Completions* buffer, and the
second TAB will then bring up the *Completions* buffer.
It happens to be my favorite behavior.

We could have
t = what it means now
nil = what it means now
eager = what you suggest (always show the completions and update them
after each key stroke)
lazy = what complete.el does for non-nil non-t values

Indeed. The closest is icomplete-mode.
