Most of the manuals delivered with Emacs are missing from
`info-look.el', for looking up Emacs-Lisp commands, non-interactive
functions, options, and other variables.

I believe that a fix for this is to replace the :doc-spec value here:

(info-lookup-maybe-add-help
 :mode 'emacs-lisp-mode
 :regexp "[^][()`''',\" \t\n]+"
 :doc-spec '(;; Commands with key sequences appear in nodes as `foo' and
             ;; those without as `M-x foo'.
             ("(emacs)Command Index"  nil "['`']\\(M-x[ \t\n]+\\)?" "['']")
             ;; Variables normally appear in nodes as just `foo'.
             ("(emacs)Variable Index" nil "['`']" "['']")
             ;; Almost all functions, variables, etc appear in nodes as
             ;; " -- Function: foo" etc.  A small number of aliases and
             ;; symbols appear only as `foo', and will miss out on exact
             ;; positions.  Allowing `foo' would hit too many false matches
             ;; for things that should go to Function: etc, and those latter
             ;; are much more important.  Perhaps this could change if some
             ;; sort of fallback match scheme existed.
             ("(elisp)Index"          nil "^ -+ .*: " "\\( \\|$\\)")
             ("(cl)Function Index"    nil "^ -+ .*: " "\\( \\|$\\)")
             ("(cl)Variable Index"    nil "^ -+ .*: " "\\( \\|$\\)")))

with this :doc-spec value:

'(;; Commands with key sequences appear in nodes as `foo' and
  ;; those without as `M-x foo'.
  ("(emacs)Command Index"                nil "['`']\\(M-x[ \t\n]+\\)?" "['']")
  ;; Variables normally appear in nodes as just `foo'.
  ("(emacs)Variable Index"               nil "['`']" "['']")
  ;; Almost all functions, variables, etc appear in nodes as
  ;; " -- Function: foo" etc.  A small number of aliases and
  ;; symbols appear only as `foo', and will miss out on exact
  ;; positions.  Allowing `foo' would hit too many false matches
  ;; for things that should go to Function: etc, and those latter
  ;; are much more important.  Perhaps this could change if some
  ;; sort of fallback match scheme existed.

That covers all of the manuals I get with `emacs -Q', which have indexes
with entries for Emacs-Lisp commands, functions, options, and variables.

Please do that, or something similar, so such symbols get picked up by
`info-lookup'.  I used the same order here as the manuals are presented
in the top-level menu.  You may want to change the order.  Another
possible change you might want to make is to use a value similar to the
one for "(emacs)Command Index" for other "(...)Command Index" entries.

["(efaq-w32)Indexes" should probably be included conditionally, for MS
Windows.  And perhaps on other platforms `emacs -Q' gives a different
set of manuals, so other adjustments could be made.]

Note that `info-lookup' is used by 3rd-party libraries, so this will
help them as well.

It seems like there should be an easy way to just _add_ such missing
entries after the fact, e.g., in a 3rd-party library.  For example, I
was thinking that perhaps `info-lookup-add-help' (without the `-maybe')
would take care of that.

But apparently not.  While trying that I found I had to reset the
various global values in `info-look.el' - once the alist and cache are
defined there doesn't seem to be a way (already provided) to update them.
`info-look.el' seems a bit monolithic, in this regard.  But perhaps I'm
missing something.
