Stefan, Lars: any comments?

I'm okay with installing this on master, but please rename the new
function to something like prog-fill-reindent; the "fill" part should
appear in the name, to explain why we have both prog-indent and this
function.

Also, a NEWS entry and some addition to the "Multi-line Indent" node
of the Emacs user manual would be nice.

Bonus points for adding something that could use treesit.el
capabilities, when those are available, instead of syntax-ppss, to
determine when we are in a comment or in a string.  Or maybe Theo or
Yuan could suggest such an addition.

Thanks.
