'self.assertLocationCommentPresent(\'django.po\', 42, \'dirA\', \'dirB\', \'foo.py\')
verifies that the django.po file has a gettext-style location comment of the form
`#: dirA/dirB/foo.py:42`
(or `#: .\dirA\dirB\foo.py:42` on Windows)
None can be passed for the line_number argument to skip checking of
the :42 suffix part.
A string token can also be passed as line_number, in which case it
will be searched in the template, and its line number will be used.
A msgid is a suitable candidate.'
