Hopefully the mesh module won't be off for long :) In the meantime,
multiple files changed to implement the Python shell. If you want to
backport it, you'll have to use svn to look at the history and see
everything that changed. This is technically feasible, but you'll have
to do the homework.

This is by-design - the Python shell works like any other - once you
enter a command with the "return" key, it becomes part of the shell
history. Editing it after the fact wouldn't make any sense, since the
command has already been executed by the Python interpreter. You seem
to want some kind of hybrid between a text editor and an interactive
interpreter. I'm open to the idea, but I've never seen such a thing.
Got an example?

A scripted node executes its script whenever its output needs to be
updated, so it isn't clear how one would use an interactive shell in
that context.
