Thanks for looking at it!

The test case creates history like this:

where b, c, bc, and cb all reference different submodule commits.
Isn't the merge search asked to search for a descendant of "b:sub" and "c:sub"
during the recursive part of the merge and then "bc:sub" and "cb:sub" during
the primary merge? Might those results be different?
As for the UI part, I think the user would be interested only in the search
results for the primary merge between HEAD and MERGE_HEAD. Results from the
intermediate merges might not make sense.
Thanks,
