i looked at your e-mail and tried it out in Practical Ruby.  Very cool how
much is accomplished by such a simple algorithm!

i noticed that "begin/rescue" and "elsif" were missing.  i believe this
can be handled the same way as the other keywords?  (diff follows this e-mail)


i suppose the next step would be to handle:

  [1, 2, 3].each do |n|
    puts n
  end

... which i guess is a matter of dealing with keywords that don't begin
the line.


i imagine that some of the other smart editing features may require that we
actually run the document through a full-blown ruby parser.  do you think
it would be advantageous to use the resulting parse tree for smart indent
and folding as well?
