bug#29462: 24.4; eval-when-compile won't mute warning as says in info doc

[Emanuel Berg <moasen@zoho.com>]

In (info "(elisp) Warning Tips"), it says

   * If you use many functions and variables
     from a certain file, you can add
     a ‘require’ for that package to avoid
     compilation warnings for them.
     For instance,

          (eval-when-compile
            (require 'foo))

However that won't mute the warnings.
Using (eval-when-compile (require 'cl-lib)) it says

    In end of data:
    wrap-search-cp.el:133:1:Warning: the
    function `cl-find-if' might not be defined
    at runtime.

Perhaps that should be `eval-and-compile', or
plain `require'?
