does and to watch out for side effects. Add FIXME for memory leaks.
Fix comment about checking for matching byte order. Preserve
pointer to old tdata (if any), and restore it if we don't match
file with target vector. If we are going to use goto's, use them
consistently and maintainably.
* nlmcode.h (nlm_object_p): Expand comments about leaked memory
to note that the problem is even more serious than just leaked
memory. Replace goto with more traditional return.
