I think it is more of a "I don't recognise this as special syntax; it
must be text".  In that case, I'm not sure what can be documented, one
can have infinitely many text blurbs which look very similar to valid
Org syntax but isn't.

I have noticed quite a few posts on the list with this kind of
misunderstanding.  I think the confusion arises from thinking of special
keywords like "#+options:", "#+attr_latex:", etc as comments.  AFAIU,
they are not.  Lines starting with "#+" are possible keywords, whereas
lines starting with "# " are comments.

I can see how that can be confusing, but can't think of a way to resolve
this.  I have two possibilities in mind:
1. change "# " to something more distict like: "//", or "##",
2. use different faces for the two.

(1) is probably too big a change, whereas (2) might be feasible.

Nicolas will probably have a better feeling about what is more
appropriate here.

Cheers,
