This is as close as I got to making this shorter... given the likely data HyperZonk gave.

#!/usr/bin/perl -p
s{^([^:]+):(\s*(?:([\da-f]{2})\s*)+)\s*(.+?)$}
 {\t"$2",\t\t/* $1: $4 */}x;
s/([\da-f]{2}\s)/x$1/g;
s/" | "/"/g;

I got it down to three regexs, the last one as a kludge...
I am sure if I have spent more time with this, I could have worked it out.
