The `screen` program has the ability to perform the 'erase_chars'
behaviour, using an ECMA-48-standard CSI X; for example:

  $ echo -e "ABCDEF\e[3G\e[2X"
  AB  EF

correctly erases the 2 chars in the middle when run via screen.

However, the `screen` terminfo file fails to include the `erase_chars`
capstring:

  $ infocmp -L1 screen | grep erase_chars
  <no output>

as compared other terms that do; for example:

  $ infocmp -L1 xterm | grep erase_chars
          erase_chars=\E[%p1%dX,

This capstring should be added to the screen terminfo. (and likewise
screen-bce, screen-256color, screen-256color-bce)

maybe/maybe not: there are a few descriptions where ECH is not used
because the terminal's treatment of bce differs from that used in ncurses.

I can investigate it (again)...

In a quick check, vttest screen 11.6.5 shows the problem I mentioned.
