Templates still require input argument, params alone not enough like docs suggest

[cmardiros]

I've been following the docs here https://llm.datasette.io/en/stable/templates.html and for me the following hangs:

llm -t recipe -p ingredients 'sausages, milk' -p country Germany

but adding an extra "input" at the end works fine:

llm -t recipe -p ingredients 'sausages, milk' -p country Germany "dinner"

I believe this is due to the fact that a prompt is still waited on from stdin. I am not sure if that is the intended behaviour but the docs suggest that the prompt defined in the template should be sufficient but it's not so perhaps just a small clarification is needed in the docs.
