If the only reason for this was the trivial one-liner conflict, the
real fix is to just not do the merge at all, and not worry about
conflicts.

I handle simple conflicts like this in my sleep. It's actually much
better and clearer if the development trees just do their own
development, and not worry about "Oh, Linus will get a small conflict
due to other changes he has pulled".

So what I did was to actually try to generate the tree I think it
*should* have been, and just merge that with the simple conflict
resolution.

You might want to double-check it - not only because I rewrote your
pull to not have the merge at all, and in the process modified things,
but just to see what I think the right approach would have been.

Now, there *are* reasons to do back-merges, but no, "Oh, there's a
trivial conflict" is not one of them.
