Fix combined diffs on merge commits

A bad automated refactoring led us to try and obtain the EditList for
a combined diff patch script.  These scripts don't have any edits,
because there is more than old image involved in each range.

Fix the code to rule out a combined diff format script and do not
access its EditList when creating the cache entry.
