Fixed.

> +Translator Comments
> +^^^^^^^^^^^^^^^^^^^

> +If you have a string where you feel that translators will need a bit of help
> to understand what it does, you can add a translator comment to it.
> Translator comments are particularly useful when you are working with
> placeholders, because you can tell the translator what the placeholder will
> be replaced with. Translator comments need to be inserted into the code in
> the line directly above the translation. Each line of a translator comment
> has to be prefixed by ``-- TRANSLATORS: ``, like this:
> +
> +.. code-block:: lua
> +
> + -- TRANSLATORS: This is just a test string
> + -- TRANSLATORS: With a multiline comment
> + print _ "Hello Word" -- Will print in German: "Hallo Welt"
_ has been explained in the Calling conventions above, but I added a new
section to explain it anyway. Removed the comment.

> +If you have multiple variables in your script that you wish to include
> dynamically in the same string, please use ordered placeholders to give
> translators control over the word order. We have implemented a special Lua
> function for this called ``bformat`` that works just like the

> + local world = _("world") -- Will print in Gaelic: "saoghal"
> + local hello = _("hello") -- Will print in Gaelic: "halò"
> + -- TRANSLATORS: %1$s = hello, %2$s = world
> + print (_ "The %1$s is '%2$s'"):bformat(hello, world) -- Will print in
> Gaelic: "Is 'halò' an saoghal"

> +Numbers in Placeholders
> +^^^^^^^^^^^^^^^^^^^^^^^
> +
> +Not all languages' number systems work the same as in English. So, mocking
> up an example with putting Gaelic grammar on an English word for
> illustration, we would have something like `0 boat`, `1 or 2 bhoat`, `3
> boats`, `20 boat`... So, instead of using ``_`` to fetch the translation, any
> string containing a placeholder that is a number should be fetched with
> ``ngettext`` instead. First, you fetch the correct plural form, using the
> number variable and ``ngettext``:
> +
> +.. code-block:: lua
> +
> + pretty_plurals_string = ngettext("There is %s world" , "There are %s
> worlds", number_of_worlds)
> +
> +
> +Then you still need to format the string with your variable:
> +
> +.. code-block:: lua
> +
> + print pretty_plurals_string:format(number_of_worlds)
> +
> +If you have a string with multiple numbers in it that would trigger plural
> forms, split it into separate strings that you can fetch with ``ngettext``.
> You can then combine them with ``bformat`` and ordered placeholders.

> +Handling Long Strings
> +^^^^^^^^^^^^^^^^^^^^^
> +
> +If you have a really long string, check if there is a logical place where
> you could split this into two separate strings for translators. It is easier
> for translators to translate smaller chunks, and if you should have to change
> the string later on, e.g. to fix a typo, you will break less stuff. The
> strings will be put into the translation files in the same order as they
> appear in the source code, so the context will remain intact for the
> translators.
> +
> +Also, please hide all formatting control characers from our translators.
> This includes HTML tags as well as new lines in the code! For an example,
> have a look at ``campaigns/atl01.wmf/scripting/texts.lua``
