Some issues with idiff

Verdict: disputed: one of the two checks found quoted evidence (not counted as a flag).

idiff doesn't support Eq, and it also doesn't support f(x) instead of y. Both should be easy to correct.

Disputed: one of the two checks found a pointer to the fix, the other found nothing. Not counted as a flag; the quote is on the task page.
