These extra examples were added just recently (v4.14-rc1)
by the commit fd46cd55fbc5a8e8c ("printk-formats.txt: Add examples
for %pF and %pS usage"). They were supposed to help using
%pF and %pS correctly according to the situation. But we
have a better solution now. %pF is obsoleted by this
patchset.
IMHO, it is perfectly fine to remove the extra examples.
