I don't see what's the problem here: if indent/ruby.rb contains:

  if a == 2
    puts "hello"
  else
    puts "there"
    puts "there"
  end

then presumably the bug would get caught.  You may have to run the test
by first flushing all the code to the left margin before reindenting,
but if reindentation works correctly both when started "at left-margin"
and when started "at the correct indentation", then there's a very high
probability that it will work in most/all other cases as well.

Do you know of bugs that have occurred and that wouldn't be caught this way?

I still don't see what problem this is trying to address.
