No problem outside of Screen with either setting.

  $ echo $TERM
  xterm-color
  $ touch a b c && ls -1 a b c | xargs vim
  Vim: Warning: Input is not from a terminal
  3 files to edit

  $ setenv TERM screen
  $ touch a b c && ls -1 a b c | xargs vim
  Vim: Warning: Input is not from a terminal
  3 files to edit
  $ echo $status
  0

What should I set TERM to here?  I tried setting TERM to "screen" and
"xterm-color".  Same problem with both.

I don't know how I could check this since the Screen window is closing 
before I get a chance to do "echo $status".

No. I am not sure what version of xargs it is either. It is part of
the SUNWcsu (Core Solaris) package on my Solaris 10 system.
