Thank you.

Ok, thank you for investigating, confirmation appreciated.  How did
you install?  I'd like to try the same method.


Here, bash readline bindings appear to be 'vi-insert', but I am not
doing this in
~/.inputrc.  I am investigating my local configuration (conf files,
macports, etc.) ; most of which I did not produce myself.

$ bind -V | grep keymap
keymap is set to `vi-insert'


This is clearly no longer "bug" related.  Is this too specific an
issue for the mailing list?


Thank you,
Richard
