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.

WT-12868 created a workaround for newly added 0-length files, however Jasmine's PR also has some deleted 0-length files. Each of these files can generate either a deleted file record in the diff, or it may generate a record moving that file to another location as it sees a match in the (0-length) content.

The solution is to also exclude from the diff output file:

• Any deleted files
• Any moved files where the record includes the path of a 0-length file.
