But you read the rendered manpage, the output of running groff (and co.)
on the manpage source, right?  If you were to read manpage sources with
less in the terminal there wouldn't be reflowing either, naturally.

The point I was making is that newlines in groff_man pages did not seem
to be more semantic than those in adoc/md/rst/whatever.  Upon rendering,
paragraph lines are reflowed.  After Robinson's explanation I can see 1
bit of meaning to them (sentence delimiters).

I guess there are although I don't personally use one (of course, that's
the point of these "light markup" formats: they mostly look like plain
text so you don't much need a renderer).  For example, there are plenty
of tools to convert these formats to HTML which can then be viewed in a
terminal browser.  Or one could use pandoc to convert them to *roff
and... haha ;).
