filectx: fix return of renamed How is this not blowing up everywhere? It seems that filelog.renamed has always returned False (incorrectly a boolean) instead of the assumed None. Tracing through history, you need to skip over my move of code in 2013 by annotating from 896193a9cab4^ and you can see the original code is from 2007 (180a3eee4b75) and that ab9fa7a85dd9 broke this by assuming renamed was a bool (instead of None). Refactoring memctx code later exposed this bug.
