Hi,
unfortunately I don't know anything about Philipp Lehmann, too, but I
solved the biblatex-bug I reported in
<
http://sourceforge.net/tracker/?func=detail&aid=3440683&group_id=244752&atid=1126005>.
Since you started an interim biblatex home at GitHub, it probably would
be best to integrate the solution there.
It's basically just a wrong positioned % in the following definition in
the biblatex.sty-file:
\protected\def\blx@finentry@usedrv{%
\unspace
% \blx@initunit
}
There are no spurious blanks anymore in multicite-commands if you
replace the code above by:
\protected\def\blx@finentry@usedrv{%
\unspace\blx@initunit
}
Please let me know if/when you include this patch.
Thanks!
Sebastian
