--bibtex and --biber were just running bibtex and biber on the
resulting diff, but this is rarely what users want. What --bbl does is
much more sensible: it generates *.bbl files on old and new versions,
and use these *.bbl to compute the diff. No run of bibtex or biber is
needed on the diff, since the *.bbl are latexpand-ed into the *.tex
source file.
Change the meaning of --bibtex and --biber to do what --bbl used to
do. --bbl is now an alias for --bibtex, and --biber does the same as
--bbl, but using biber to generate the *.bbl file.
Old, essentially broken options are kept with different names
--run-bibtex and --run-biber, but I suspect to one is really using
them. We break backward compatibility, but the benefit of having short
and sweet option names for things that work should be higher than the
cost of backward compatibility.
