annotate Python/import.c @ 39753:8dcb882ec3e1 legacy-trunk

Bug #1520864 (again): unpacking singleton tuples in list comprehensions and generator expressions (x for x, in ... ) works again. Sigh, I only fixed for loops the first time, not list comps and genexprs too. I couldn't find any more unpacking cases where there is a similar bug lurking. This code should be refactored to eliminate the duplication. I'm sure the listcomp/genexpr code can be refactored. I'm not sure if the for loop can re-use any of the same code though. Will backport to 2.5 (the only place it matters).
