What is the test case that results in this error message?

I'm not sure if this is worth the complexity, but when I got the error "orderfields: structs must have same fields up to order", I thought that it may be useful to indicate which fields were different.

The patch is less trivial than I expected, and probably not worth the maintenance burden, but since I have written it, I'll post it here once I have the bug number.  Currently, if only one field is in one struct but not the other, it prints the name of that field; otherwise it prints the number of such fields.  There are many more verbose possibilities (like listing all shared/LHS-only/RHS-only fields if that number is below a threshold), and I'm happy to implement something different if people think it is worth it, but I'm afraid of the tail wagging the dog.
