revert removing double spaces in some styles.
I'm deleting double spaces after checking in the following styles:
annalen-des-naturhistorischen-museums-in-wien.csl
canadian-journal-of-fisheries-and-aquatic-sciences.csl
genetics.csl
journal-of-forensic-sciences.csl
liverpool-laureate.csl
london-south-bank-university-numeric.csl
moorlands-college.csl
owbarth-verlag.csl
the-open-university-numeric.csl
the-open-university-numeric-superscript.csl

The following journals have a commented out macro--the macro itself is non-sensical, but if it's going to be useful the double space should be deleted, so taking those out too:
din-1505-2-alphanumeric.csl
din-1505-2.csl
din-1505-2-numeric-alphabetical.csl
din-1505-2-numeric.csl
fachhochschule-vorarlberg-alphanumeric.csl
(these are all commented out)
