Re: screen's terminfo src is missing hpa= and vpa=...?

[Tor Perkins]

update:

  I had it wrong before and broke a different app (debian's aptitude).

  Now, these seem to work well for screen's terminfo source file:

    hpa=\E[%i%p1%dG, vpa=\E[%i%p1%dd,

  Why does screeninfo.src not include these capabilities...?

  Screen guru's please enlighten me!  :^)
