roxygen2 7.3.1

• S3 method export warning no longer fails if class contains { or } (#1575).

• @family lists are now ordered more carefully, "foo1" comes after "foo"
  (#1563, @krlmlr).

• @importFrom works again for quoted non-syntactic names, e.g.
  @importFrom magrittr "%>%" or @importFrom rlang `:=`
  (#1570, @MichaelChirico). The unquoted form @importFrom magrittr %>%
  continues to work. Relatedly, @importFrom directives matching no known
  functions (e.g. @importFrom utils plot pdf) produce valid NAMESPACE files
  again.

• Multi-line @rawNamespace no longer break re-runs of namespace_roclet()
  (#1572, @MichaelChirico).
