Re: indentation indicator at document root

Hmmm. I don't recall this being brought up at the time. Good questions.

Ingy's proposal to eliminate the integer indicator and replacing it with
the position of the `|` would have avoided it, but we didn't think of it at
the time (a pity).

At any rate, a literal reading of the spec does give rise to the
interpretation you gave. I guess we have to live with it? At least until
such time as we have 1.3 or something of that sort.

Nice catch...
