Re: obsolete comment in tool-bar.el

[Luc Teirlinck]

I forgot that the argument to defcustom gets evaluated outside the
:initialize function.  I will implement another solution.  Also,
tooltip-mode can not use custom-reevaluate-setting, because it would
load tooltip on systems where we decided it should not be loaded.  So
I will undo my change to startup.el and put in a comment explaining
why all the stuff I replaced really is necessary.  The autoload for
tooltip-mode probably should be removed now that it is preloaded on
systems on which it makes sense.

Sincerely,

Luc.
