Like the previous patch, this cuts down the number of str*cmp calls in read_directory (which does _a lot_). Again sorted results on webkit.git:

treat_leading_path: 0.000 0.000 read_directory: 3.674 3.558 +treat_one_path: 2.427 2.305 ++is_excluded: 2.221 2.098 +++prep_exclude: 0.224 0.223 +++matching: 1.650 1.529 ++dir_exist: 0.035 0.035 ++index_name_exists: 0.288 0.291 lazy_init_name_hash: 0.257 0.257 +simplify_away: 0.085 0.086 +dir_add_name: 0.441 0.445
