Fix [[* completion when there is text after point 

* lisp/org-pcomplete.el (org-parse-arguments): Parse text between [[*
and point as a single "argument" for pcomplete.  This avoid weird
breakage when treating every space-separated text in the line as an
argument.
(pcomplete/org-mode/searchhead): Do not alter `pcomplete-stub' - it is
no longer necessary as `org-parse-arguments' now takes care about not
including * and ] into the stub.

Warning! pcomplete code is rather tricky and it is not always clear if
Org's approach is not overusing internals of pcomplete.
