I don't think they should cause problems unless they depend the presence of
methods not present in 2.4 and 2.5, but that only affects 1.7. It is hard
to say what things will cause problems in advance, but I suspect most
things won't be difficult. If the ws_comma fixer is run and committed after
1.8 is released, there might be cherry-picking problems that would make
backports a bit more work. There are also a couple of fixes yet to go in
that involve version dependent imports, memoryview/buffer in particular,
that would be a good to have in 1.8.
