The original description suggests jj somehow converts line endings, when in fact all it
does is commit files as is (as described in the previous paragraph), whether the line
endings are CRLF or LF.
According to the discussion on Discord, streampager is still maintained.
It brings more dependencies, but seems more reliable in our use case. For
example, the streampager doesn't consume inputs indefinitely whereas minus
does. We can also use OS-level pipe to redirect child stderr to the pager.
