Ingo Schwarze has rewritten the printf(3) man page for OpenBSD. I think the result is a huge improvement and I would like to suggest that FreeBSD incorporate this rewrite. https://cvsweb.openbsd.org/src/lib/libc/stdio/printf.3
Return to the pool since I currently didn't have the time to work on this.
This update looks real good and quite clear. I am looking at seeing how these updates can be incorporated and suggested for an update to this particular manual page.
This manual page has been reviewed and changes to the FreeBSD printf(3) manual page have been submitted, via pull request. Details of the updates are pending review but more details are available here: https://github.com/freebsd/freebsd-src/pull/1149
