ZPT is supposed to be using XML, and in XML, all new line characters get
converted to the equivalent of '\n', regardless of the OS.  SO this
needs to happen.

However, neither the attribute value nor Python would care if there were
line feeds in the example locations or not - as long as they were real
line feeds and not escape characters, anyway.

If the TAL expressions were truly XML, and one wanted line breaks, they
ought to read like this -

"python:test( no_types == 1
,
  'Add New ' + types[0].Title()
, 'Add New Item')"
