Note: filename is allowed to be NULL here.
This is a bug in the existing code that you just moved.
I suggest moving error printing into buffer_init().
This way the basis for the message is clearer.
For bonus points, we should split buffer_init().
Plain buffer_init() should use stdin.
The new buff_init_path() should take a filename.

Otherwise, I like the direction of this patch.
