fixup-features formatting

Sometimes fixup-features does things like this:

@@ -28,13 +28,14 @@ full = [
     "tor-bytes/full",
     "tor-llcrypto/full",
     "tor-units/full",
-    "tor-error/full",
+    "tor-error/full", "equix?/full", "tor-memquota?/full",
 ]

And then it has to be manually fixed up.
