in reply to peek - output a one-line preview of stdin

my $pad = ' ' x $wide;
...
$_ = substr($_ . $pad, 0, $wide);
print $_, "\r";

That can be written far more simply and efficiently as:

printf "%-${wide}.${wide}s\r", $_;

Great tip-- I often forget to use printf, as if moving from C to Perl meant having to leave all of C's methods behind. I have never liked the %#.#s notation of printf... and now I imagine perl6's interpolated hashes may make for some righteous DWIM hacks.
