___S_A_G_E___ encoding in the notebook

[Ondrej Certik]

Hi,

if you execute this in the notebook:

print "___S_A_G_E___"

the cell will get deleted and "</pre>" will endup instead of it.
That's a bug, but you might argue that noone should be executing this
in the first place.

Thanks. File a ticket. For now I think the best "fix" is to detect
that on input and do something to it, e.g., transform it to : "hah, I
see you read the notebook source code and realized you might be able
to break the notebook by sending __SAGE... as input. :-)"
