In the "Files to Fix" field, if I try to specify "-*/.jpg, -*/.png", it does not seem to exclude all .jpg and .png files recursively, as your example for file patterns says it should. The image files become corrupted after being built because it attempts to fix the line endings on them.

The closest I can get is to explicitly exclude entire folders, however we have a very large source tree, and if an image file gets moved, then it's broken. When I exclude by entire folders (not by filename extensions), the images are no longer corrupted.
