AFAIK `time` is clearly a bug in the tree-sitter grammar.
E.g. it probably causes a misparse for things like:

time while ... do ... done

That was my impression as well.

The same probably holds for `coproc`.
I suspect that for the other ones it doesn't make much difference, OTOH.
So maybe the other ones were deliberately omitted to keep
the grammar simpler.

So maybe I should just use a more generic query and use a regex to fontify the keywords. Something like this:

(command_name ((word) @font-lock-keyword-face

(:match <rx string regex here> @font-lock-keyword-face)))
