Spurious spaces with oc-biblatex

[Denis Maier]

Hi,
Elias and I have run into an potential bug in oc-biblatex:
======================================
#+cite_export: biblatex authoryear

[cite:@doe] => ok

([cite:@doe]) => this generates a space between the opening parentheses 
and the citation.
======================================

Result:

========================================
\autocite{doe}

( \autocite{doe}) => this generates a space between the opening 
parentheses and the citation.
=========================================

Best,
Denis
