#nsub!(*args) ⇒ Object

Usage: self.nsub!(/foo/, 'bar')

nsub! is like gsub! except it logs the calling method in @changed_in. There is another difference: When using blocks, matched strings are available as block params, e.g.: # nsub!(/(match1)(match2)/) {|m1,m2|}

I wrote this because I was having problems overriding gsub and passing a block from the new gsub to super.
