CMSG_DATA.3: Fix formatting of printf escape sequences
Escape sequences like "\n" have to be escaped twice in examples in our mdoc(7)-based manual pages in order to be displayed properly. The problem is that otherwise they are interpreted by mdoc(7), which results in: printf("parent: received '%s'0, buf); being shown to the user instead of: printf("parent: received '%s'\n", buf); Approved by: bcr (mentor) MFC after: 2 weeks Differential Revision: https://reviews.freebsd.org/D24056
