Depends on the definition of "correctly", but perhaps you have a
definition different from ours ;-) The "patches" shown with -c/--cc are
designed to be different from normal diff so that people do not
accidentally try to apply them with "patch" or "git apply".

"log -p" omits merge commits by default because diffs of merges are mostly
not useful for ordinary purposes.  If you are trying to use "log -p" to
reproduce a (part of) history, perhaps you would want to also study -m
option.
