Improved implicit pandoc-citeproc inclusion.

The filter pandoc-citeproc is automatically used when
`--bibliography` is specified on the command line, unless
`--natbib` or `--biblatex` is used.

However, previously this only worked if `--bibliography`
was spelled out in full, and not if `--biblio` was used.
This patch fixes that problem.
