termcap and bce causing headaches

[Peter Beckman]

I'm using Alpine and it wants to do the right thing and respect the termcap
entry for the terminal it is running in.  Very reasonable.

So I learned that for some reason background-color-erase (bce in terminfo,
ut in termcap) wasn't being set.  A bit more reading led me to see that I
needed to put "defbce on" in my .screenrc and then all would be well.  So I
did.

It's not (or I'm confused).

When I start screen, I can confirm it's using the right term:

    --> echo $TERM
    screen-bce

Even tset -s tells me that :ut: is set in the termcap (it's the first entry):

    --> tset -s
    Erase set to backspace.
    set noglob;
    setenv TERM screen-bce;
    setenv TERMCAP

    unset noglob;

The strange thing is, $TERMCAP set :ut: cannot be found:

    --> setenv
    [..]

(also strange, echo $TERM works, but echo $TERMCAP does not. using tcsh)

I also did a "dumptermcap" and got the same thing -- no sign of :ut:.

My $TERM before starting screen is "xterm", here's the output from tset:

    --> tset -S
    xterm

So _I THINK_ I'm doing it right, but I'm getting unexpected results.  Using
screen 4.00.03 (FAU) 23-Oct-06 on FreeBSD 6.2-RELEASE-p5, screen is
compiled from FreeBSD ports.
