Hi,
I would like to ask anyone for a help with formatting references to a block in ISO-690 (numeric, Czech). According to actual style (http://www.zotero.org/styles/iso690-numeric-cs) references are formated like this:

1. LEVY, Howard I., Brett HANSCOM a Scott D BODEN. Three-question depression scree-ner used for lumbar disc herniations and spinal stenosis. Spine. 1. červen 2002, roč. 27, č. 11, s. 1232–1237.

but I would like it in this format:


1. LEVY, Howard I., Brett HANSCOM a Scott D BODEN. Three-question
__depression screener used for lumbar disc herniations and spinal
__stenosis. Spine. 1. červen 2002, roč. 27, č. 11, s. 1232–1237.


I guess a part of a source code from line 330 should be changed. Now the code is::

<bibliography>
<sort>
<key variable="citation-number"/>
</sort>
<layout>
<text variable="citation-number" suffix=". "/>
<choose>

I discussed about it at https://github.com/citation-style-language/styles/pull/206 where you can see I tried to change the source code (see below), but it still doesn´t work.

<bibliography entry-spacing="0" second-field-align="flush">
<sort>
<key variable="citation-number"/>
</sort>
<layout>
<text variable="citation-number" suffix=". "/>
<choose>

Please, can anyone help me with this style? It is one of the most used citation style at the Czech universities, so that´s why I am so interested in to make this style correct.

Thank you in advance for any help.
