Code Issues Proposed changes

Include a magic /MERGE_LIST file for merge commits

Browse Source 
The /MERGE_LIST file is generated by Gerrit and is automatically
included in all changes for merge commits. It contains a list with the
commits that are integrated by accepting the merge commit. When
comparing against the auto-merge or a previous patch set it is assumed
that the first parent is uninteresting, so that the file lists all
commits which are reachable by the other parents, but not by the first
parent. If a comparison against a selected parent is done, that parent
is marked as uninteresting. This means the content of the file depends
on the selection in 'Diff Against' drop-down box.

By having the /MERGE_LIST file reviewers can immediately see which
commits get integrated by this merge commit. This is important since
for merge commits reviewers are supposed to review and approve these
commits. Having a file for this allow reviewers to comment on the list
and also see diffs between patch sets.

In edit mode the /MERGE_LIST file is not editable.
