:) This has been discussed in probably hundreds 
of posts in the last 2-3 years. The range of
opinions is something like this:
  a. It's a bug
  b. It's a feature
  c. It's an oddity
  d. It's too late to fix it easily
  e. Various combinations of the above

Go do a search for "block-local"... that should
turn up lots of insomnia-curing material.
