@densh Code fixed
@retronym It's a version of printAnnotations method for TreePrinter. ParsedTreePrinter overrides this [method](https://github.com/VladimirNik/scala/blob/3989227e45a8b7f56da59b7ce674706b1e99279b/src/reflect/scala/reflect/internal/Printers.scala#L663) and process back-ticks for special characters. In the case of TreePrinter arguments to the annotation are printed as a part of tree because toString results in invocation of TreePrinter's printTree(annot).
