Subject: Can't think

I'm too tired to think this out for myself, and I can't find it in the 
pickaxe, so I'm going to be lazy and bug the list; no doubt someone will see 
the solution right away.

I want to do this:
  mystring.split("\n").delete_if{ |s| s =~ /^\s*$/ }.join("\n")
using gsub ('cause it'd be nicer). So what I'm doing is removing those lines 
that consist of only whitespace. I tried this:
  mystring.gsub(/^\s*$/, "")
This removes the whitespace, but not the newline, like the above one does. So 
really, the question is how do I get the regexp to match the newline?
