Hi,

Thanks for the answer. However I can already achieve the behaviour you describe 
by adding the following to my previously described inputrc:
TAB: menu-complete

I would like not to have to do that - I like the way that with my current 
inputrc binding as listed in my first post, completion just stops at the common 
prefix when I hit tab. So with the same directory listing in the example above 
I can do the following:
# Type 'ls d'
$ls d
desktop/  document/ dropbox/  
$ ls d

# Type 'o', then press <TAB>
$ ls d
desktop/  document/ dropbox/  
$ ls document/

I would like the choice between the completion mechanism I used in my first 
post (manually cycling through completion options), and the completion 
mechanism in this post (typing extra characters onto the common prefix and then 
completing again).

In any case, the behaviour I described in my first post still seems like a bug. 
I don't see why, under any circumstances, it make sense for bash to display the 
same completion list twice.

Many thanks,

Rehan
