This only works if its on the first or second form in a block.  I think this is
because the indentation code only checks those and then assumes the same
indentation for every following line in the same block.  This is probably OK as
I can't imagine too many instances where you need to randomly change the indent
midway through a block, and in those cases you can just stick this on the first
