intl_migration: doesn't handle triple-quoted multi-line strings properly

[alanknight-wk]

It generates a single-line, without a closing quote, and does not properly distinguish two similar large strings.

I noticed it also doesn't handle strings with an explicit newline in them. This makes me think that the problem may not be with getting the data out of the analyzer, but with the way we generate it. Because when it fails I also see lines at the end of the file that look like the rest of the problem declaration. So maybe if there's a newline in the literal string something weird is happening with the way we do the output.

Hmm, I bet this is where I do something along the lines of

  var lines = classFile.readAsLines();
  lines.sort();

Because I made the assumption that new lines would always be escaped, but that doens't hold true form triple quote strings.
