Review Request #180 — Created Nov. 29, 2016 and updated — Latest diff uploaded
This is not perfect, but this should fix 99% of the cases. This will still show incorrect filenames if path looks like /path/to b/your/file, but hopefully that should be pretty rare.. Testing Done: Tested with the dev server. Fixes bug 3558. Reviewed at https://reviews.reviewboard.org/r/6466/
