Something like C-x C-e, but without actually executing the command.

So ble-bind -m 'emacs' -f 'C-x C-e' edit-and-execute-command is cool, and it emulates the same feature in readline. However, would it be possible somehow to have the command not immediately executed after exiting the editor?

You can define your own widget by modifying the implementation of ble/widget/edit-and-execute-command. For example,

# blerc

function ble/widget/Knusper/edit-command {
  ble-edit/content/clear-arg
  local ret=
  ble/widget/edit-and-execute-command.edit "$_ble_edit_str"
  ble/string#rtrim "$ret"
  ble-edit/content/reset-and-check-dirty "$ret"
  _ble_edit_ind=${#_ble_edit_str}
}
