PATCH: prevent filling of #+ lines

[Dan Davison <davison@stats.ox.ac.uk>]

This patch prevents fill-paragraph from acting on lines that start
with #+ (optionally preceded by spaces or tabs).

For example, at the moment if you have

#+HTML: some html here
Long line of normal text here and it goes on and on and on and on and on and on and on

And then issue fill-paragraph (M-q) on the "Long line of normal text..." line, I
end up with

#+HTML: some html here Long line of normal text here and it goes on
and on and on and on and on and on and on

With this patch I get

#+HTML: some html here
Long line of normal text here and it goes on and on and on and on and
on and on and on

Same problem for paragraphs below source code blocks, etc.
