[O] Typo in 'org-without-partial-completion'

[Paul Sexton]

I think there's an error in 'org-without-partial-completion' in org-macs.el.
The variable pc-mode gets bound to the value of partial-completion-mode - but 
this is a VARIABLE (t if that mode is enabled). Funcalling the value of 
the variable produces an error, unsurprisingly. This breaks insertion of 
properties with 'org-set-property'. 

Fixing it involves quoting the the symbol as shown below:


(defmacro org-without-partial-completion (&rest body)
   `(let ((pc-mode (and (boundp 'partial-completion-mode)
                        'partial-completion-mode)))   ; <-- quote added
      (unwind-protect
          (progn
            (when pc-mode (funcall pc-mode -1))
            ,@body)
        (when pc-mode (funcall pc-mode 1)))))
