In a range-diff it's not always clear which file a certain funcname of the inner diff belongs to, because the diff header (or section header as added in a previous commit) is not always visible in the range-diff. Add the filename to the inner diffs header, so it's always visible to users. This also allows us to add the filename + the funcname to the outer diffs hunk headers using a custom userdiff pattern, which will be done in the next commit.
