These are code improvements to the 5ae2087202, which answer critics in
the thread.  0001 comprises an optimization, but it's rather small and
simple.  0002 and 0003 contain refactoring.  0004 contains better
error reporting.  For me this looks like pretty similar to what others
commit post-FF, isn't it?
