 children in summary line
Date: Mon, 24 Feb 2025 07:34:02 +0800

I think this change is fine (I'm already using it:)).  It would be good
to also update the gnus manual to mention these two new threading
variables.

Also, the box drawing vertical lines have large gaps, so I set
`line-spacing' to nil in gnus summary buffers, which minimizes (but does
not eliminate) the gaps. Is there an alternative?
