Indeed :)

Thank you.  See below.

After looking at the code some more, you're right in that reading kcbt
is unnecessary.  However, if KEY_BTAB isn't defined, but the backtab
escape sequence is supported (as it is under Slang, at least), the
fake SHIFT_TAB key is still needed as a placeholder.

So here's an updated version of the patch: I've resynced it with
current git (e2843ed) and made it a proper git patch, it no longer
unnecessarily reads kcbt, and I've updated the comment describing
which systems treat Esc [ Z as backtab is updated using the info here
as best I can:

http://invisible-island.net/ncurses/terminfo.src.html

(Incidentally, Eterm doesn't support backtab at all, and the above
source says iTerm supports it, but I have no idea whether iTerm2
supports it.  It's ANSI, in any case.)
