Yuck :(

Indeed.

But I'm now having the same problem inside screen (actually tmux, but they
both use the same TERM settings) because the screen and screen-256color
terminfo databases have kbs=^H.  I think we both agree that this is a bug,
and I'll email Thomas Dickey presently to report it, and get some feedback.

Actually, now that you highlight it.  *That* is actually the bug I'm
tripping:  Using Lua Zile interactively works fine without my patch, in
that the backspace key does the right thing.  Although, of course, the
stupid kbs=^H setting grabs ^H before Zile can bind it to anything more
useful, so a literal ^H also behaves like a backspace keypress.  But,
there's no reason that should hang the interactive quoted-insert test :(

Ack.  Thanks for the pointer.

I'll email Thomas Dickey, and try to root out the test suite hanging
bug (out of interest, does make check in current HEAD lua running inside
screen hang for you too?).

Would you mind writing a first cut at the documentation you want to add?
