Feature request: C-x C-e to open the current prompt inside the editor

[iamFIREcracker]

Exactly like Bash does it -- from its man page:

       edit-and-execute-command (C-x C-e)
              Invoke an editor on the current command line, and execute the result as shell commands.  Bash attempts to  invoke  $VISUAL,
              $EDITOR, and emacs as the editor, in that order.

Of course one could always get to the beginning of the line, type in /editor, and press enter, but I figured it could be a nice addition.

If there is appetite for including this, I might even try to implement this myself.
