That was, indeed, the original way to handle citations in the former
org-export-bibtex.el. It is still supported in both LaTeX, obviously,
and HTML (which will split the above among two anchors).

"cite" link support was added later, and is lacking in this area.

At the user level, a filter is definitely the way to go.

Though, it is an interesting feature to implement in ox-bibtex.el. One
idea would be to write another parse-tree filter function which would
change cite links into \cite{...} commands and consecutive cite links
into \cite{..., ...} commands.

This would also allow us to get rid of both `org-html-link' and
`org-latex-link' advices, as no more cite link would be left in the
parse tree anyway.

What do you think?
