I thought so too, but the end result didn't build, and I was unable to
figure out why.

Yes, that's the only thing I'm sure about. All changes to mydirectory
should come from my branch. If there are changes necessary to make
things build, they are better done by me.

Thanks for the suggestion. I tried following this approach, but...

Ie. when throwing out what the commit came up with.

The problem was that the end result didn't build, wit pretty much the
same obscure failures that the regular merge had.
But I eventually tried something that worked:
1. First create a local branch off master
2. Merge in mybranch with "-s ours --no-commit"
3. Checkout mydirectory from mybranch
4. Commit
5. Switch to mybranch
6. Merge in the new local branch, which resulted in a conflict-free
merge that has my changes in mydirectory and the rest of the world
in the rest of the working directory, and the history of mydirectory
looks ok
The end result built and worked.
If git had had a "-s theirs" strategy, I wouldn't have needed the
temporary branch made off master. That need for that branch is probably
the most cryptic thing for people following my instructions for future
merges.
To sum up the commands:
git checkout master
git checkout -b master_nicely_merged_with_mybranch
git merge -s ours --no-commit origin/mybranch
git checkout origin/mybranch top/middle/mydirectory
git commit
git checkout mybranch
git merge master_nicely_merged_with_mybranch
Thanks!
