The usual answer is "don't do that."

Always use a text editor to change your code on disk and re-load it by sourcing it or building it into a package. This makes sure your changes make it back to the hard disk where they came from to begin with, since the edit function only "saves" them back into your workspace.

This also eliminates the confusion of modifying nested functions separately from the functions they are nested in, since the whole function is redefined at once.
