[O] Contradiction between code and doc as regards commented lines

[Rafael Laboissiere]

Before Git commit e8046d2, lines like this were treated as comments in 
org-mode:

    ### This used to be a comment

At present, lines as the above are not highlighted as comments and will 
be exported verbatim.  Only lines like the following are considered to be 
comments, currently:

    # Only this is now a comment

This behavior is clearly in contradiction with the documentation, 
according to this relevant part of doc/org.texi:

    @node Comment lines,  , Horizontal rules, Structural markup elements
    [snip]
    Lines starting with zero or more whitespace characters followed by @samp{#}
    are treated as comments and will never be exported.

Please, fix the documentation (or restore the previous behavior, if the 
documentation is meant to be correct).

Cheers,

Rafael
