Subject: Re: Efficiency of string parsing

Excellent sollution for coding efficiency. (though, I always think  
Regular Expressions should be commented well (broken into parts) due  
to the terseness of the syntax, especially for those who don't use  
RegEx regularly. (no pun, really)

But would a Ruby iterator be faster?

Clearly this is a tool to wrap text to 50 characters per line without  
breaking words. Curious to see more ideas/approaches on that.
