It took me so long to reply partly because I remember seeing some guy
doing clever trick with tab completion that also shows a short help
text in addition to the complete words. I could not find that again
and from my reading (also internet searching) it's probably not
possible to do this without trickery.

It's not that weird if you think about file path completion, where you
complete one path component at a time not full path, bash just does
not show you full paths to everything.

I'm arguing about this because I want to see your reaction, because
I'm thinking of doing the very same thing for config completion. Right
now "git config <tab>" gives you two pages of all available config
variables. I'm thinking that we "git config <tab>" just shows the
groups, e.g.

> ~/w/git $ git config
add.              interactive.
advice.           log.
alias.            mailmap.
am.               man.

Only when you do "git config log.<tab>" that it shows you log.*
