After enabling the eol extension and re-checking out my working copy, I've applied the patch successfully, but after I do so, I get this error when trying to open the solution in VS2010:

"One or more projects in the solution were not loaded correctly"

and

C:\Users\jaraco\projects\public\cpython\cpython\PCbuild\pythoncore.vcxproj : error  : The imported project "C:\Users\jaraco\projects\public\cpython\cpython\PCbuild\pythoncore_d.props" was not found. Confirm that the path in the <Import> declaration is correct, and that the file exists on disk.  C:\Users\jaraco\projects\public\cpython\cpython\PCbuild\pythoncore.vcxproj
