Nope. In this case, n == 1 so the line does not match. How do we know n == 1? 
Well, the productions use the same n throughout the parsing of the block 
scalar, so it can't be 2 for one line and 1 for another. Obviously, to have a 
chance at parsing the scalar, when auto-detected, n must be at most the 
minimal indentation actually used, which in this case is 1. Of course, this 
means means the scalar _still_ doesn't parse, so its in error.

This is convoluted because you are saying it in BNF; this special error case 
is also explicitly covered in the accompanying text, in a way that probably 
is a better match to how things work in a parser in practice.

At any rate, I'll add an error example to the spec covering this.

Have fun,
