If you think that's the correct solution, sure.

You said you will install that if no one objects.  I'm not sure what
was the conclusion of the discussion with Eshel about that.  If it's
unrelated, then please go ahead and install your changes in that
discussion.  In any case, perhaps you could help Eshell improve and
polish his additions, which AFAIU are supposed to provide an optional
behavior more similar to the previous one.

Thanks.
