Nice detailed yet easy to follow report you posted at that pastebin.
I would suggest, nowever, to include such report in the email itself
another time, either inline or as attachment. Unlike IRC, email does
not get as cluttered by including details, and can be used offline.
This very issue I could have answered without going online to fetch
that pastebin web page, had the info been contained in the email.
Just a suggestion for small improvement of your already great report :-)

The cause of the problem is most likely that at some point in the past
the upstream git derived from the contents of upstream tarballs - or
perhaps some bogus commits was made to the "upstream" branch, not only
merging from upstream git or importing tarballs.
You can manually adjust the files failing to merge automatically. The
contants should match the merged in upstream git, so you probably want
to remove the upper parts and preseve to lower parts of merge hints in
the files. I believe this is not very crucial, however, as any errors
here is shadowed anyway when afterwards importing the corresponding
The safer apprach - which might also avoid the problem reappearing with
future merges - is to "reset" the "upstream" branch to use upstream
git checkout -b v87 reset-upstream-to-v87
git merge --strategy ours upstream
git checkout upstream
git merge reset-upstream-to-v87
git branch -d reset-upstream-to-v87
Above commands first create a branch from the v87 tag, pseudo-merges
HEAD of upstream branch into that, and then merges back the result on
top of the "upstream" branch and cleans up the temporary branch.
The psudo-merge keeps current content but fakes that another branch have
been merged into it. The git merge strategy "ours" does this, but lack
the opposite which is what we really needed here - hence the juggling
with a new branch so as we temporarily can be standing on the alien
branch we want to keep and merge in the one we want to override.
Hmm. Not sure this was very clearly described. Perhaps read the
section on MERGE STRATEGIES in "git merge --help".
 Obviously I go online to fetch my emails too, but separately: I
mirror all my emails to my laptop using offlineimap, and often respond
to emails while offline - e.g. sitting in a train or at places with
unreliable internet access.
