Pass cursor position to edit_command_buffer for some editors

Browse source 
Fixes #6138

Naturally this does not work for many other editors/aliases,
but it's still nice that we can make it work for some common
editors without requiring any configuration.

Of course this approach is not terribly flexible; but it's
alwyas possible to just wrap edit_command_buffer and set an
EDITOR that knows about the cursor position. It doesn't
feel important enough to add a configuration option.
