That ".gsub(/^  /, '')" at the end of the template is the clue. It
deletes the first two spaces at the beginning of each line.
The '%' modifier works only at the very beginning of each line. If you
change either the indent of the template to two spaces
or change the gsub to replace the same number of spaces you've
indented by, the example will work.
