Flatten out the if statements in match_stat_with_submodule so the
logic is more readable and easier for future patches to add to.
orig_flags didn't need to be set if the cache entry wasn't a
GITLINK so defer setting it.
Thanks for splitting this change out. I have to say I find the original
quite a bit easier to read. If you're worried about the code added in
the next commit being too indented perhaps you could move the body of
the if statement into a separate function.
Best Wishes
