helpful-function doesn't show documentation about helpful HOT 4 CLOSED

Left is helpful-function, right is describe-function.

Nope, that's not expected. Every function should show its documentation.

I can't actually reproduce this:

I'd initially guessed the issue was autoloading, but I'd expect to see 'this function has not been loaded' in the *Help* buffer if autoloading was the cause.

Are you seeing this with other functions?

I cannot reproduce anymore. I will reopen when and if it comes back. Sorry for the noise.

I have an idea what happened here.

Earlier versions of Helpful only supported functions, so buffers only stored the symbol. Now that we support both variables and functions, there's a helpful--callable-p that needs to be set.

I'm guessing that you reloaded an existing results buffer after upgrading? That would have had helpful--callable-p as nil, so it would be trying to show the docstring of a variable called shell-quote-argument.
