/**
* Many lists in FontForge are singly linked. At times you might want
* to append to the list which, when you only have a pointer to the
* start of the list can be more verbose than one would like. To use
* this macro you must defined a null initialized variable 'last'
* outside of any loop that traverses the source list. The last
* variable is used used by this macro to quickly append to the list
* as you go. This macro also assumes that the 'last' and 'newitem'
* types have a member "->next" which contains the single linked list
* pointer to the next element.
*
* Efficient list append should really be a one line call in the bulk
* of the code :)
*
* example:
* MyListObjectType* newfoolast = 0;
* MyListObjectType* newfoolist = 0;
*
* for( ... iterate a source collection of foos ... )
* {
* MyListObjectType* foocopy = CopyIt( foo );
* FFLIST_SINGLE_LINKED_APPEND( newfoolist, newfoolast, foocopy );
* }
