Oh, I think I've solved this. :)
$ cat prefix.pl
#!/usr/bin/perl
use strict;
binmode STDIN;
binmode STDOUT;
STDOUT->autoflush(1);
my $needed = 1;
while (1) {
my $char;
my $bytes = sysread(STDIN, $char, 1);
exit 0 if ($bytes == 0);
if ($needed) {
print "# ";
$needed = 0;
}
print $char;
$needed = 1 if ($char eq "\n");
}

This also, I think, solve the "recursive TAP output" issue too, since
sub-tests will be entirely contained in the #-indented output and
could be parsed out of the diagnostics by just doing a 2-character
left-strip.
Thoughts?
