Exactly, thanks for explaining.
Here's a patch.
Very few places need adjusting. Those that do are all places that are
currently manually discarding the build number as irrelevant.
Note that emacs --version no longer outputs the build number.
I'm wondering if M-x emacs-version can omit the build number too.
I think it unlikely that anyone using M-x emacs-version cares about it.
BTW, I see in elpa.gnu.org that company.el and diff-hl-dired.el
compare emacs-version against strings including build numbers
("24.4.51.5"), which again seems to indicate confusing the build
number for something meaningful.
