Re: [PATCH v3 21/22] diff: free state populated via options

Patrick Steinhardt [off-list ref] writes:

The `objfind` and `anchors` members of `struct diff_options` are
populated via option parsing, but are never freed in `diff_free()`. Fix
this to plug those memory leaks.

Thanks.

Even though "diff" is generally my bailiwick, I've never paid
attention to these features (hence the resources they consume and
leak).  The patch looks good to me.
