There were no objections, so I've now done this in Emacs 28.  (It didn't
seem NEWS-worthy, so I didn't add a NEWS item.)

Witch that change, I think Noam's approach to handling EOF characters in
non-interactive Emacsen should work fine, so I'm closing this bug
report.  If more work needs to be done here, please respond and we'll
reopen the bug report.
