history-search-backward doesn't work with operate-and-get-next(C-o)

[Vandrus Zoltán]

Hi,

I usually run two commands in bash after each other:
  xgamma ..
  xbacklight ..

I bound C-<up> to history-search-backward, so typing 'xg C-<up>' recalls
xgamma in history. Then I would expexct C-o to run xgamma and recall the
xbacklight command. But it doesn't happen.
It works, with the default bound incremental backward search, 'C-r xg' though.

On ArchLinux, with
bash 5.1.008
readline 8.1.001

Regards,
Zoltán
