Bazaar has a cool feature called "Merge directive" that packages all changes relative to the partent branch: http://doc.bazaar.canonical.com/bzr.2.2/en/user-guide/sending_changes.html

It would be cool if Fossil supported this feature as well

I think the DVCS way to do this is:

1. Clone original repository.
2. Make your changes.
3. Send pull request, as in: "Hey, I've got this fixed, pull from https://url"

Right, that's the standard heavyweight way. Merge directive is a lightweight way of doing this. I think of is as series of commits represented as individual patches. The benefit over a single patch is that history is preserved. Maybe this feature isn't as important for Fossil. (I changed Severity of 'Minor').
