That may be a good idea, it would prevent potential name clashing with
the created bib file.  Currently, the function creates a
<name-of-org-file>-combined.bib file with the content of all
bibliography files, then bibtex2html creates
<name-of-org-file>-combined.html and
<name-of-org-file>-combined_bib.html.  Passing the contents via stdin
would skip the <name-of-org-file>-combined.bib.  We could achieve the
same by simply deleting <name-of-org-file>-combined.bib after calling
bibtex2html.  I personally don't mind leaving the .bib file after
processing, but if there is a consensus to limit the side effect, we can
do that.

As far as the implementation goes, I am not sure what is the best way to
get this to work with stdin.  In the attached patch (which does *not*
work) I tried to use `call-process-region' and dump the bibliography
files into a temporary buffer.  This complicates the code a little.
Alternatively, we could use the `INFILE' parameter from `call-process',
but it looks that this would require a file, so it would not change much
from the previous patch.

Any thoughts?
