status: create class for status lists Callers of various status() methods (on dirstate, context, repo) get a tuple of 7 elements, where each element is a list of files. This results in lots of uses of indexes where names would be much more readable. For example, "status.ignored" seems clearer than "status[4]" [1]. So, let's introduce a simple named tuple containing the 7 status fields: modified, added, removed, deleted, unknown, ignored, clean. This patch introduces the class and updates the status methods to return instances of it. Later patches will update the callers. [1] Did you even notice that it should have been "status[5]"? (tweaked by mpm to introduce the class in scmutil and only change one user)
