Sheet name with blanks not getting returned by DefinedName.destinations
*Created originally on Bitbucket by [fumitoh (fumito hamamura)](https://bitbucket.org/%7Be7522b08-69c1-493a-a459-5e68c9aaae68%7D/)* As you can see in the code below, when a defined name refers to `"'Sheet 1'!$A$1"`, `None` is returned as the first element of the tuple returned from a call to the generator destinations. `m.group('quoted')` instead of `m.group('notquoted')` should be returned in such cases. ``` #!python # defined_name.py, line 133 @property def destinations(self): if self.type == "RANGE": tok = Tokenizer("=" + self.value) for part in tok.items: if part.subtype == "RANGE": m = SHEETRANGE_RE.match(part.value) yield m.group('notquoted'), m.group('cells') ```
