Realistically, there seems to be only two ways you could solve this: built-in VCS support in the software used to edit these files or exporting them to line-based text and dealing with them like we currently do. Building support for millions of formats (and their countless variants when created by different software and even versions of the same software) into the VCS system itself I strongly suspect would be futile. The VCS would end up much bigger and more complex than the OS.
