Here's a patch incorporating some of the points other people have made:
diff --git a/doc/emacs/modes.texi b/doc/emacs/modes.texi
index c1564e9..c8da68a 100644

run @code{prog-mode-hook}, prior to running their own mode hooks.
Hook functions can look at the value of the variable @code{major-mode}
to see which mode is actually being entered.
Any objections to me installing this in the Emacs-25 branch?
