Re: edit-and-execute-command; minus the "execute" part?

One workaround would be to bind the keystroke to a macro that inserts
a comment character at the beginning of the line before doing
edit-and-execute-command. Then when you exit the editor the comment
will be "executed" then you can press up arrow to retrieve the line
and delete the comment character and do further editing then execute
it.

This does all of that for you. At the command line:

bind '"\C-xp": "\C-a# \C-x\C-e\C-p\C-a\C-d\C-d\C-e"'

or in ~/.inputrc

"\C-xp": "\C-a# \C-x\C-e\C-p\C-a\C-d\C-d\C-e"

You could bind it to some other keystroke if you'd like.

It relies on everything having default bindings. At a Bash prompt,
with a command line showing, press Ctrl-x followed by p. Your command
will be shown in your $VISUAL (or $EDITOR or emacs) where you can edit
it (don't remove the # and space at the beginning of the line). When
you exit the editor, The "comment" will be "executed", it will then be
retrieved and the "# " removed, the cursor will be moved to the end of
the line ready for you to do whatever you'd like.

It might be easier
