Dear All,

the attached patch substantially improves the formatting of CSL-based
bibliographies in LaTeX export by supporting in-style formatting
settings that were previously ignored, most importantly,
'second-field-align', which is typically used for numeric styles such
as ieee.csl.

I'm sending this while another oc-csl patch (about affix and locator
formatting) is still under discussion because I consider it a priority
for the 9.6 release. (Not supporting those formatting settings
rendered a large number of styles, some of them pretty popular, close
to being unusable.)

Thanks in advance for your feedback!

best wishes,
András
