When a conflicted submodule is selected, the main view shows the commits
each side added relative to their common ancestor as two indented logs,
labelled current and incoming, so it's clear which commit each side would
resolve to.
The logs aren't truncated (the view scrolls). If a side added no commits
of its own (e.g. it was rewound to an ancestor of the other), its head
commit is shown instead.

When both sides of a merge moved a submodule's gitlink, git reports it as "UU".
Pressing space used to fall into the submodule no-op guard and pop the confusing
"Nothing to stage..." error, and enter just entered the submodule, which does
nothing to resolve the superproject conflict.
Treat a conflicted submodule like the other non-textual conflicts: both space
and enter now open a picker offering the two candidate commits, "current" and
"incoming", each labelled with its summary. `git checkout --ours/--theirs` is a
no-op on gitlinks, so we resolve by checking the submodule out at the chosen
commit and staging it.
