"any pages" includes the possible value 1; there's no need for "()".
Please use semantic newlines. See man-pages(7).
$ MANWIDTH=72 man man-pages | sed -n '/Use semantic newlines/,/^$/p'
Use semantic newlines
In the source of a manual page, new sentences should be started
on new lines, long sentences should be split into lines at clause
breaks (commas, semicolons, colons, and so on), and long clauses
should be split at phrase boundaries. This convention, sometimes
known as "semantic newlines", makes it easier to see the effect
of patches, which often operate at the level of individual sen‐
tences, clauses, or phrases.Have a lovely day!
Alex
