While we install /etc/inputrc (not sure where, must be from the newer isos),
that's useless if there's no ~/.inputrc file with a line with '$include
/etc/inputrc' in it.

Adding that to your home directory will fix it (then relogin/rexecute bash so
readline library picks it up.).  Perhaps this needs to be added to our new user
skel (do we even install one of those?)

We don't configure stuff for the users... we leave it for them to configure it.
Though I belive iuso was messing with adding a custom inputrc. Yup it's in INSTALL.

It should be an optional feature of readline and zsh, default to off, of course,
but this is a rather _basic_ thing we can automate for people, so I do want it
in there, so we don't have to have people figure it all out on their own.

Yeah optional that's how it should be done... on all... Also thi inputrc was
created by iuso but he seems to have forgotten to add a queary to install it or not.

Yeah, please knock him over the head and get him to add a query.  That violates
our policy.  If we're automating part of something we do really need to have it
work, and hcnce this bug is valid as a result.

I reopened bug 10021.

I've done stuff with 10021, please have a look. I'd like to know if xterm and 
others still behave like this with the latest readline when /etc/inputrc is 
selected for install. Anyone?

This now applies to stable grimoire (0.22).
