Fixes this bug:

    C completion: doesn't work after aa[0]->, where aa is an array of
    structures.  (W. de Hoog, 2006 Aug 12)

If one types 'aa[0]-><Tab>', the list "items" in
runtime/autoload/ccomplete.vim:ccomplete#Complete() gets the value
['aa', '[0]', ''].  items[1:] is then used as lead for the script function
s:Nextitem(), but this is wrong, as the element '[0]' then becomes a part of
the lead.  This patch fixes it by always using the last element in items as
lead, items[-1].
