Re: org-habit config tinypatch

I found the issue, and it's a more subtle one.  I've set a bug to emacs
list in case they think it's a documentation or fixable bug.  What
happens is this:

    - The custom value setting for org options do not take effect until *after* the relevant lisp code has been executed once.  This means:
    - If you start emacs and immediately go into *scratch* and print org-habit-show-today-all you get an error because that variable has not yet been bound.
: Debugger entered--Lisp error: (void-variable org-habit-show-all-today)
:   (print org-habit-show-all-today)
:   eval((print org-habit-show-all-today) nil)
:   eval-last-sexp-1(t)
:   eval-last-sexp(t)
:   eval-print-last-sexp()
:   call-interactively(eval-print-last-sexp nil nil) 
    - If you start emacs and immediately go into options->config for org-habit, the org-habit-show-today-all will indicate that it has been set outside of the customization system when the intended value is "t".  When the intended value is "nil" there is no indicated problem.
    - If you start emacs and put a buffer into org mode, the (print org-habit-show-all) will show the customized value, and the options->config will also show the customized value.

I think that this is either a documentation bug, where this behavior
needs explaining, or a bug in customize.  As a naive user of customize I
would expect that going to the org-habit group would automatically
trigger applying the org-habit customizations.  Opening an org-mode
buffer has this effect.

But, perhaps there is some flag somewhere well hidden in the
documentation for customization groups that needs to be set to indicate
this.
