If you fold, then comments no longer apply, since the branch has changed.

So, what you should do to maintain comments? Don't fold commits after you open your pull requests, just keep committing on top. You can add **[FOLD]** tag in the commit message, if you want a patch to be folded. 

Then when you are happy and ready to have this merged, you can either fold once, or you can let Vinnie or I fold for you when we merge the code into develop.
