Thanks for the quick reply Chet.

I should have insisted on the fact that I don't want the first TAB to insert
a full match. The first TAB should only insert the longest common prefix
between all the possible completions (not a full match). A full match should
only be inserted from the second TAB hit.

Let's say I have the following files in the current working directory:
aaaaaa aaabbb aaaccc.
Then if I type 'cat a<TAB>' at the prompt, I should get a list of all the
possible completions and the longest common prefix inserted (that is 'aaa').
With menu-complete, 'aaaaaa' would be inserted, which is a full match, not
the common prefix. If I press TAB one more time, then 'aaaaaa' should be
inserted.

Hope it is a bit clearer.

Cheers,
Julien
