Hmm...  I do not see anything you added to this header file that needs
such a forward declaration.  Other files you added that include diffcore.h
may want to have that declaration, but I do not think this header file does.

Please describe what these fields mean.

Isn't "range" too generic a term?  Unless you make this as a static
declaration only visible to functions where "range" can only mean "line
ranges" in their context, that is.
