[issue12864] 2to3 creates illegal code on import a.b inside a package

[simohe]

New submission from simohe <simohe at besonet.ch>:

When the current module is in a package and imports submodules, the following lines are converted to illegal code.

-import sub.subsub
+from . import sub.subsub

-import sub, sub.subsub, sub2
+from . import sub, sub.subsub, sub2

A valid alternative:

-import sub.subsub
+from .sub import subsub as _dummy

-import sub, sub.subsub, sub2
+from . import sub, sub2\nfrom .sub import subsub as _dummy
