Yeah.

I was wondering about that, but I couldn't really find any situation
that gave any difference. But I've added it now.

Right - thanks. However, this makes me wonder - should we really be
setting mark here? I see that c-indent-defun does not, and it feels
weird that indenting adds to the mark ring. What do you think? My
first patch used
(indent-region
(treesit-node-start node)
(treesit-node-end node))
Which behaves similarly to c-indent-defun.
See attached patch.
Thanks,
Theo
