Looks like the changelog checker doesn't like me combining two PRs in CHANGES.md, let me know if you prefer separating them.

Looking at diff shades, this explodes:

-man_pages = [
-    ("index", doc_module.__name__, doc_module.__name__ + " Documentation", [""], 1)
-]
+man_pages = [(
+    "index",
+    doc_module.__name__,
+    doc_module.__name__ + " Documentation",
+    [""],
+    1,
+)]

-    c = Context({
-        "version": get_docs_version(),
-    })
+    c = Context(
+        {
+            "version": get_docs_version(),
+        }
+    )

I'll take a look later.

diff-shades finally succeeded after several retries.

I tried my best to read through the preview diffs, and they all look expected to me.
