In 09-1-35.pdf pages 1-5 and half of page 6 indent by 2 spaces
the other half of page 6 indents by 3 spaces. On page 7 they indent
by both 2 and 3 spaces back and forth over several lines. page 8
onwards again indent by 3 spaces. I'm ignoring labels and comments
and such that all appear to be unindented. So the machine used to
print the source code seems not to be well behaved.

But since indenting by three spaces would consume more diskspace
and it may have been a scarcity, perhaps that would be an argument
for tabs..?
