Minimal workaround to solve the PATH environment variable contains '+' c...

I created a potential workaround for the issue of the PATH environment variable containing '+' characters.  If I understand the code correctly, I believe this workaround will silently ignore any folders in the path that contain the '+' character. I would anticipate this most likely occurring on anyone who has notepad++ installed and in their PATH directory.  I've included a commented printf statement if anyone wants to use it to verify that the change detects the '+' sign correctly.
