Description

Since my last post in T48683 wasn't answered, I have decided to create a new report so it will be easier to keep track on things.

System Information
Intel Core i7, 8 Gb RAM, AMD Radeon HD 7700
Windows 7 x64

Blender Version
Broken: 2.77 fad0c33
Worked: 2.76b f337fea

Short description of error
After the recent changes in Knife tool, a knife cut creates polygons with inverted normals.

Exact steps for others to reproduce the error
Create a default UV Sphere and try to cut some polygons in a way like on provided picture. As a result you will have one of the corners with inverted normal. There was a hole there, it is gone now, but now there is an inverted polygon on its place. You can use my test file: open the file and try to cut selected polygon or any of its neighbors.
