I find your sig very appropriate.  I can find several ways to clean up a 
string using two or more operations, I was just looking to see if there 
was not also a way to do the same thing with one operation.
In some ways Ruby is far easier to use than the language I have been 
using for over 25 years, but there are other places it is much harder. 
I am doing a lot of experimenting to find out the best way for me to do 
things and this is the latest experiment.
