[sf-perl] IPC::Open3

[David Alban]

Actually, this works, too, and is what I'll do when I want stderr
separated from stdout.[1]  Unless someone has a better idea.

    open my $efh, '>&', \*STDERR or die "$pgm: can't dup stderr: $!\n";
    my $pid = open3( my $wfh, my $rfh, $efh, qw( ls -ld foo bar ) );

[1]  Do folks here who use open3 just intermingle them?
