debugdiscovery: include the number of heads in all sets

We already displayed information about heads of the common set that are either
local or remote heads. We now also do so for heads of the common set that are
both local and remote heads too. This is useful because various step in the
set discovery algorithm have head specific optimizations.

Remove a file that was added via merge. Since the file is not in parent 1,
it should not be in the diff.

Rename a file that was added via merge. Since the rename source is not in
parent 1, the diff should be relative to /dev/null
