ignore: fix path concatenation of .hgignore on Windows Since 3de48ff62733, .hgignore is ignored on Windows because a pat may have a drive letter, but pathutil.join is posixpath.join. "z:\foo\bar/z:\foo\bar\.hgignore" Instead, this patch uses os.path.join() and util.localpath() to process both parts as file-system paths. Maybe we can remove os.path.join() at dirstate._ignore because 'include:' is resolved relative to repo root? It was introduced by a04c7b74b3d5.
