Comment (by gschoppe):

 In the process of writing unit tests, I discovered that get_file data()
 seems to not support single line file header declarations, such as

 {{{#!php
 <?php // Template Name: Test ?>
 }}}

 This may be why the code was not previously using get_file_data().  I am
 now looking into whether it is feasible to add support for single line
 headers to get_file_data() as this lack of support seems to be an
 oversight, and this format needs uniform syntax across all use cases.
