just golfing yours:
perl -nle'print$1?("$1 repeated ",length($&)/length$1," times"):$&whil
+e/(\w+?)\1+|./g'
You don't need the brackets around the time(s), because any time it's less than two, you only print out one character. You were matching \w, so I didn't check for defined on $1, just $1, but it should give the same results.
I think that's 75, not including switches.
