Readline only works a line at a time.  If the calling application needs to
build commands of more than one line, like bash, it constructs them from
multiple calls to readline.  Bash does its best to retrieve mult-line
commands from the history list and allow the `v' command to edit them, but
it can always be made better.

I'm not sure what you're trying to do with the `g, since it's not bound to
anything.  The `v' command is described in
