[New-bugs-announce] [issue18477] fix_import (2to3 fixer) is not case-sensitive

[ProgVal]

New submission from ProgVal:

In a project, I have a package with a module named Socket.py, and the __init__.py imports the "socket" module (from the standard Python lib).
However, when fix_import went over it _on Windows_, it converted "import socket" to "from . import Socket".
I also had this issue from a package containing a subpackage named "Math", and a __init__.py importing "math" (from the standard Python lib).

This issue is caused by using os.path.exists(), which is case-insensitive on Windows. However, PEP 235 says imports are case-sensitive.

I'm including a patch I have wrote for this.
