When I explicitly launch man, I am going to read the top of the man page
and some place in the middle, so "less" is useful.
When I launch some nix build-related tool I expect to monitor current
progress, and read the last 50 lines if something fails (something like
tail -f, but for a stream).
For nix-store --help a pure listing of all the options without any other
text would probably be an improvement over showing man page (for my
For git logs, by the way, tac would fit my use case better than less.
But the PAGER really matters for man, so I keep it set to 'less -R'
