Alternative to escaping new lines is replacement:

irb(main):004:0> s="foo
irb(main):005:0" bar
irb(main):006:0" baz".gsub! "\n", ' '
=> "foo bar baz"
irb(main):007:0> s
=> "foo bar baz"

Of course, this is less efficient because it's done at runtime - but 
might be ok for constants.

This also works with heredocs.
