OK we need to fix that :)

You're mis-reading the code. What it's actually doing is removing any
newlines *at the start of the main body*. Now, in a normal paragraph,
that's not really needed (beginningOfBody() == 0 then).
But when we have a manual label (e.g. in a list), allowing a newline at
the very start of the body (which starts after the first space) causes
LaTeX errors, since it's not allowed. So we have to prevent the user
doing it.
