I've attached a patch that adds the BCE functionality I did before.
It's more concise this time. You have to apply the other patch first,
the one that does pane colors for bce terminals.
As for the other stuff, I misunderstood what you were referring to. I
thought you were looking for a different implementation of bce support
for what I had already done. I'll take a look at getting full
support.
