For clarity: the hanging indent filter above inserts `\item` in front of 
every entry, and requires the definition of a  `references` environment in 
a template:

~~~
\newenvironment{references} {\list{}{% hanging indent, 
src/myfilters/addRefEnvItem.hs
    \leftmargin1.5em%
    \itemindent-\leftmargin%
    \itemsep0.5ex%
    \parsep0pt%
    }}
    {\endlist}
~~~

I wonder whether the latex writer itself shouldn’t insert such a 
`references` environment by default. Hanging indent is required by many 
styles anyway but could be redefined as necessary.

Even better, pandoc(-citeproc) could parse the CSL `hanging` and 
`second-field-align` flags, and inject appropriate formatting instructions 
into the `references` environment.
