When comparing a patchset with another one, the added and deleted files
were not displayed properly:
-change 1,1 is adding file a, c and deleting d
-change 1,2 is adding file a, b and deleting d
When comparing 1,1 to 1,2, the file changed list should show that b was
added and c was deleted but instead it was showing that only b was
added.
When comparing 1,2 to 1,1, the file changed list should show that b was
deleted and c was added but instead it was showing that only c was
added.
I know that this behavior was intended[1], i.e. when comparing patchset
with each other, the file list will not include files not in the base.
The problem is that behavior was perceived as a bug by our users. When
they compare patchset between each others, they expect to see the full
list of files changed, even if the file is not in the base.
