Comment 4 for bug 750421

The attached branch removes the never-shown "Review Infringment" string for translation, along with a second string that is also never actually displayed ("Reported by" ). I also added a comment to the translator before each of the four combobox entries as shown:

 #. TRANSLATORS: The following is one entry in a combobox that is
#. located directly beneath a label asking 'Why is this review inappropriate?'.
#. This text refers to a possible reason for why the corresponding
#. review is being flagged as inappropriate.
#: ../utils/submit_review.py:997
msgid "Contains inaccuracies"
msgstr ""

Hopefully, this does this trick! Simon, Lucian, please let us know if this indeed takes care of the problem and we will work to get this fix merged and released as quickly as we can so we don't impact your team further with this. And thanks very much!
