Don't fold over horizontal rule line break

Heading fold should stop at horizontal rule

Currently heading fold will fold until the next heading with the same level.
However when a page has a horizontal rule ---, it’s a clear indication that this is a logical break between text, therefore fold should stop at this line. Not every time I use a --- the following section need to have a header with the same level as the previous headers.

# H1
Fold with H1
## H2
Fold with H1
## Another H2
This should not be folded with H1 above.

Alternative: Consider horizontal rule also as a fold marker, with priority bigger than H1 header. This way one can fold the entire --- section regardless of what header is used inside.


+1 I use the horizontal rule as a divider between major sections in the doc in exactly this way. It provides a visual distinction especially when looking at a long list of collapsed H1s or H2s etc.
