The other problem is that right-angle bends tend to concentrate etchant and may result in over-etching the trace a bit in the corner. Presumably it can lead to a break in the trace. For most of us, that's the reason why we don't use right-angle corners. The electrical effects become noticeable if you're doing multi-GHz boards.
