* Pass pathFilters as an array Otherwise, when we try to iterate over pathFilters in the filesystem utils module, we end up iterating over each character in the filter string, which ends up generating 'Filter error_ Missing [ in filter expression.tid' as the tiddler's filename Fixes GH #4173 * Allow for multiple path filters to be specified ...via $:/config/FileSystemPaths, split by newlines
