bug#60006: 28.2; C-h f reports wrong version

[Ikumi Keita]

C-h f reports wrong version when `always' was introduced.

[How to reproduce]
1. emacs-28.2 -Q
2. Type C-h f always RET
3. Then *Help* buffer says:
  Probably introduced at or before Emacs version 1.1.

This contradicts to the following entry in etc/NEWS:
----------------------------------------------------------------------
** New function 'always'.
This is identical to 'ignore', but returns t instead.
----------------------------------------------------------------------

That's why it says "Probably".  The method of finding out the first
release where the symbol appeared is a heuristic, and it can sometimes
fail in ridiculous ways.

For me, it is: "Probably introduced at or before Emacs version 25.1."

Just out of curiosity, what heuristic exactly?

NEWS.25 says:

    *** New value 'always' for 'sh-indent-after-continuation'.

I don't think there's much we can do here besides redesigning this
feature from the ground up.  So I'd be inclined to close this one as
wontfix.
