If the bibtex-completion-additional-search-fields variable is set (say to include tags), should not bibtex-completion-format-entry add the field(s) to its output?
bibtex-completion-candidates does include the additional fields, so I was expecting that to carry through with the formatted output.
Bottom line, for #361 or #355, how do we include the additional field(s) in the string that gets completed against?
