"C-h f always RET" says:

   always is a byte-compiled Lisp function in =E2=80=98subr.el=E2=80=99.
   [...]

     Probably introduced at or before Emacs version 25.1.
     This function does not change global state, including the match data.

However, 'always' only appeared in Emacs 28, so that information is
misleading when trying to write backwards compatible code.

(It's less of a problem when the version that is shown is greater than
the actual first release, which I think happens more often.)

Not sure how to fix this. Maybe exclude common English words (which
are likely to appear in NEWS* without being the name of a function)
from scanning in help-fns.el?

help-fns--first-release-regexp is supposed to find only quoted names,
so the problem is not with common words.  I think it finds this in
NEWS.25:

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

So maybe we should reject matches that immediately follow "value" or
"values".  That won't reject all false positives, but it should be an
improvement, I think.

NEWS.26, too (twice):

  ** Option 'buffer-offer-save' can be set to new value, 'always'.
                                                         ^^^^^^^^
  When set to 'always', the command 'save-some-buffers' will always
              ^^^^^^^^
  offer this buffer for saving.

So we have more prefixes to filter out: "set to" as well.  And some
punctuation between "value" and a quoted symbol should be ignored.
