Do

  $ emacs -Q test.el

and type `kill-emacs' and see what happens.

It gets buttonized to the help if used in ERC, I think that's
cool and helpful as well, for example in #emacs.

In the Emacs help tho it gets buttonized/hyperlinked as well
but converted to (respelled as) ‘kill-emacs‘, even if put as
`kill-emacs' in a docstring.

That notation, i.e. ‘kill-emacs‘, however does not get
highlighted/buttonized/hyperlinked in ERC, I don't know if
that is by intent.

Again take a look at the screenshot to see what happens:
