bug#44386: 28.0.50; icomplete-mode with arg t stopped working

[Pankaj Jangid <pankaj@codeisgreat.org>]

I have this in my startup file:

--8<---------------cut here---------------start------------->8---
(add-hook 'emacs-startup-hook
	  (lambda ()
	    (icomplete-mode t)))
--8<---------------cut here---------------end--------------->8---

Till yesterday, it was working. In today's build it is
not. `icomplete-mode' is not active after startup.

Later, I found this in the docstring,

--8<---------------cut here---------------start------------->8---
If called from Lisp, toggle the mode if ARG is ‘toggle’.  Enable the
mode if ARG is nil, omitted, or is a positive number.  All other
values will disable the mode.
--8<---------------cut here---------------end--------------->8---

And setting `t' to `+1' worked. But I am just curious if this is a
recent change that even a truth value `t' is not enabling the mode.
