My coworker modified a lot of files which I haven't touched at all. But when I try to git pull now, a lot of conflicts appear in the files he touched, but I did not. And the conflict is on the content of the whole file. It starts with:
<<<<<<HEAD
{content of the whole file}
=========
{content of the whole file}
>>>>>>>{commit code}
I want to accept his changes, but proceed with normal conflicts if we really both modified the files. Why does this happen and how to fix it ?
