mandoc: Now that .nf and .fi are implemented in the roff(7) parser and

[schwarze]

Log Message:
-----------
Now that .nf and .fi are implemented in the roff(7) parser and formatters
rather than in the man(7) parser and formatters, document them in the
roff(7) manual, where they belong, rather than in the man(7) manual.
Mention that they imply an output line break, and mention which macros
imply these requests.
