My wikis have many places where an #ask query uses a template result format and one of the fields returned is multi-valued. I typically use #arraymap (from PageForms) to separate the values at the comma separator for further processing. However, without valuesep specified, the separator is now defaulting to a space rather than a comma even when I try to turn off the feature with $smwgResultFormatsFeatures.
I am faced with the proposition of finding all of the #ask queries in all of my wikis that use a template result format and then examining all of those templates to see if I use any #arraymap calls and then returning to the query to add "valuesep=,".
Is the fact that valuesep defaults to a space rather than a comma a bug or a conscious choice? Having sep default to a space seems to be useful, but it would be helpful if valuesep defaulted to a comma to retain the behavior of the template result format prior to 2.5.0.
