Pre-commit Review Incorrectly Identifies Files in Patch When Patch Contains "---" (3 Dashes)

Steps to reproduce:

1. Create Review in Crucible.
2. Under "Add Content" add a pre-commit patch containing "---" (use attached patch.txt for example).
3. Crucible fails to identify the files in "insertions".
4. To workaround this, just change to "-- -" (break the 3 dashes).

There is also CRUC-856 describing similar problem but marked as fixed in 2.3.6
