During her work on WT-12837, jasmine.bi@mongodb.com has encountered issue triggered by some 0-length files that are being added as part of her PR.

For patch builds, the Code Change Report creates a git diff between the patch and develop. If this contains newly added 0-length files then the pygit2 Python library used in the Code Change Report code fails to load the diff causing the task to fail.

This ticket will develop a solution so that the Code Change Report works in the presence of newly added 0-length files.
