This is to help people that for whatever reason don't want to go through the effort of changing it manually every time.

Default levels of understanding and thoroughness for both positive (review)and negative(flag) could also be configurable in the user-config file.

@
-fn func(a,b,c) {
-  x = g(a,b)
-  y = if x {
-          h(b,c)
-      } else {
-          0
-      }
-  return x + y
-}
+// fn func(a,b,c) {
+//   x = g(a,b)
+//   y = if x {
+//           h(b,c)
+//       } else {
+//           0
+//       }
+//   return x + y
+// }

It would be nice if diff-goto-source (C-c C-c) worked when this is invoked from github-review-forge-pr-at-point.

In many cases it does not matter too much whether the user has the "correct" branch is checked out - it just needs to be close.
