I had to scratch my head here for a moment. Don't we use those options
as part of the comparison?
I took the "which" to mean "the compare function", but I think you mean
"we pass these diff options already when the hashmap is initialized".
Maybe something like this would be more clear:
When we initialize the hashmap, we give it a pointer to the
diff_options, which it then passes along to each call of the
hashmap_cmp_fn function. There's no need to pass it a second time as
the "keydata" parameter, and our comparison functions never look at
keydata.
This was a mistake left over from an earlier round of 2e2d5ac184
(diff.c: color moved lines differently, 2017-06-30), before hashmap
learned to pass the data pointer for us.
(I'm just guessing on the second paragraph based on a quick look at
git-blame and my recollection from the time).
