     * Parses portable object (PO) format.
     *
     * From http://www.gnu.org/software/gettext/manual/gettext.html#PO-Files
     * we should be able to parse files having:
     *
     * white-space
     * #  translator-comments
     * #. extracted-comments
     * #: reference...
     * #, flag...
     * #| msgid previous-untranslated-string
     * msgid untranslated-string
     * msgstr translated-string
     *
     * extra or different lines are:
     *
     * #| msgctxt previous-context
     * #| msgid previous-untranslated-string
     * msgctxt context
     *
     * #| msgid previous-untranslated-string-singular
     * #| msgid_plural previous-untranslated-string-plural
     * msgid untranslated-string-singular
     * msgid_plural untranslated-string-plural
     * msgstr[0] translated-string-case-0
     * ...
     * msgstr[N] translated-string-case-n
     *
     * The definition states:
     * - white-space and comments are optional.
     * - msgid "" that an empty singleline defines a header.
     *
     * This parser sacrifices some features of the reference implementation the
     * differences to that implementation are as follows.
     * - No support for comments spanning multiple lines.
     * - Translator and extracted comments are treated as being the same type.
     * - Message IDs are allowed to have other encodings as just US-ASCII.
     *
     * Items with an empty id are ignored.
