Bug report

Python 3.11b1 raises with the following givenpath.rglob("") wherepath is apathlib.Path. This worked in previous versions (and also in whichever previous alphas GitHub Actions used).

defrglob(self,pattern):"""Recursively yield all existing files (of any kind, including        directories) matching the given relative pattern, anywhere in        this subtree.        """sys.audit("pathlib.Path.rglob",self,pattern)drv,root,pattern_parts=self._flavour.parse_parts((pattern,))ifdrvorroot:raiseNotImplementedError("Non-relative patterns are unsupported")>ifpattern[-1]in (self._flavour.sep,self._flavour.altsep):EIndexError:stringindexoutofrange

rglob isdocumented as

This is like callingPath.glob() with “**/” added in front of the given relative pattern

so I think"" is a valid input torglob().

Pretty sure this was introduced inea2f5bc/#10349.
