...to be more compliant to the »Lumiera Forward Iterator« concept. This can be easily achieved by inheriting from util::RegexSearchIter, similar to the example in CSV.hpp Regarding #896, I changed the string rendering to use fs::path::generic_string where appropriate, which means that we're using the normalised path rendering
