[PATCH v2 01/21] pathspec: save the non-wildcard length part

We mark pathspec with wildcards with the field use_wildcard. We could do better by saving the length of the non-wildcard part, which can be used for optimizations such as f9f6e2c (exclude: do strcmp as much as possible before fnmatch - 2012-06-07).
