Several bugs causing entries to be improperly filled have been fixed,
and probably countless more I was unaware of; with fill-column set to
44, for example,

* lisp/progmodes/cmake-ts-mode.el 
(treesit-induce-sparse-tree)
(treesit-node-child, treesit-node-start)
(cmake-ts-mode--imenu)
(cmake-ts-mode--imenu-1): Remove.
(treesit-search-subtree): Declare.
(cmake-ts-mode--function-name): New
function.
(cmake-ts-mode): Use it.

would have been filled to:

* lisp/progmodes/cmake-ts-mode.el 
(treesit-induce-sparse-tree)
(treesit-node-child, treesit-node-start)
(cmake-ts-mode--imenu,
cmake-ts-mode--imenu-1): Remove.
(treesit-search-subtree): Declare.
(cmake-ts-mode--function-name): New
function.
(cmake-ts-mode): Use it.

Not understanding the original code, it was not possible for me to
describe the change in greater detail.
