There is none in coreutils, but there *are* tests there that set IFS.
Just none that use these relatively new functions in an affected scope.

Good suggestion.  Setting IFS does seem prudent.
However, I'm inclined to use a subshell only if necessary:

warn_ ()
{
  case $IFS in
    ' '*)         printf '%s\n' "$*" 1>&$stderr_fileno_   ;;
    *) ( IFS=' '; printf '%s\n' "$*" 1>&$stderr_fileno_ ) ;;
  esac
}

Thanks!
