Subject: Re: use reqex to get the middle character and repeat it

ahh why didnt i just think of that...  str.gsub(/(\w)(x)(\w)/, 
'\1'+'\2'*4+'\3')

In this situation the string will always be 3 chars long and will either 
consist of spaces or x so the above will be fine (with a bit of 
tweaking).

Thanks very much!
