The <<- only does that for the EOS terminator, not for every line of the string:
2.2.0 :001 > string = <<-EOS
2.2.0 :002"> gone is music
2.2.0 :003"> yet you sing
2.2.0 :004"> EOS
=> " gone is music\n yet you sing\n"

Technically, it searches for the "least indented line" in the whole string, and removes exactly that amount from each line. So yes, the indentation problem -is- solved in ruby (though it might break entirely if you have empty lines, since the least indented line has no indentation).
