odt-bib-style.lua

--
-- Corrects the style of bibliography when converting to ODT. This is necessary
-- because Pandoc's ODT writer doesn't properly set this style.
--
-- Currently, all paragraphs in bibliography are turned into raw blocks with
-- correct style. Because of this, only italics, bold and link markups are keep;
-- all other markup is lost.
--
-- dependencies:
--   - util.lua, need to be in the same directory of this filter
--   - odt-custom-styles.lua, need to be used, and used AFTER this filter
