[NTG-context] [BIB] Extra space before surname

[Giuseppe Bilotta]

Hello,

I just noticed that there is an extra space before the
surname if there is no "von" part.

My setup:

\def\bracketed#1{[#1]}

\usemodule[bib]
\setupbibtex[database={mrabbrev,bezier}]
\setuppublications[numbering=yes,
                   sorttype=cite,
                   criterium=all,
                   numbercommand=\bracketed,
                   refcommand=num]
\setupcite[num][left={\start\bf[},right={]\stop}]
