Turn off the translation of C-[ to ESC, C-i to TAB, etc.  Only really
useful in graphical sessions, but I'd support such an option, though I'd
never use it myself.

To play devil's advocate, though, we wouldn't want this to lead to
people producing public modes whose default keybindings depend on this
translation not happening.  Hmm...  I may have just talked myself around
to not wanting the option.
