I think it's got to be the latter, because the patched LIST_LOOP macro
still has a curly brace problem, and it would require all invocations
of LIST_LOOP to add a 4th argument.  I count 174 uses of the LIST_LOOP
macro in the current code, so that seems like a daunting task.

The question that still remains is whether to fix the LISTNODE_DELETE
macro as I discussed in [quagga-dev 1295].  So far, there are no
uses of LISTNODE_DELETE except for Kir's patch.  If we are going to
keep that macro, I think it should be fixed, and it should be
used in the listnode_delete function (to reduce code duplication).
