I have a question: would someone tell me how to interpret or use an
emacs backtrace or point me to reading material?

1. Extract the patch from the email and save it to a file "thepatch"
2. cd into the repo and make sure you are on master using
   git status.
3. Hopefully git status will say 'working directory clean'. But if it
   shows that there are modified files, and *if* these modifications are
   junk resulting from your previous attempt to apply the patch then you
   can blow all outstanding changes away and revert to the last 'proper'
   commit with
   git reset --hard HEAD
4. At this point 'git status' should report that you are on master and
   working dir is clean.
5. Create a temp branch with
   git checkout -b branch-with-patch
6. Check that you are on the new branch with
   git status
7. Apply the patch with
   git apply < thepatch
8. Commit the change in the temp branch with
   git commit -am "the commit message"

Now you can restart emacs and org will pick up the modified files. To go
back to the master branch without the patch that would be

git checkout master

Make sure you don't apply the patch in the master branch.
