Subject: replacing repetition of characters in string

Hi there,

A friend of mine asked me to write a script that reads a file and
marks the double characters.
Something like:

$ ruby scratch_ruby_drio.rb
INPUT
---------
test. AA. I greatXXrr love it.
audi tt uu yes.
stop here, axmmen.

OUTPUT
------------
{3} test. *AA*. I great*XX**rr* love it.
{2} audi *tt* *uu* yes.
{1} stop here, ax*mm*en.

I coded something up that works but I don't like it:

Do you guys have any other alternatives?
