identify: build the tag list directly instead of using wctx.tags() The current implementation of workingctx.tags() returns the tags of the parents. This causes the calculation of {lastesttagdistance} from wdir() to be wrong. The value when updated to a tag is 0, but updated to the tag's child is 2, the child of that 3, and so on. This prepares for workingctx.tags() to not report the parent tags.
