In the markdown editing reference page it states that horizontal rules could be made using the following:
Insert a horizontal rule
<hr/>by putting three or more hyphens, asterisks, or underscores on a line by themselves:
Rule #1 --- Rule #2 ******* Rule #3 ___ Rule #4 - - - -
However, this is what this actually looks like:
... you will notice that the first one is a heading instead of an
hr. This is because the documentation also says that headings can be created using the following:
Header 1 ======== Header 2 --------
The number of = or - signs doesn't matter; one will work. But using enough to underline the text makes your titles look better in plain text.
There is obviously a conflict here when someone tries inserting 3 or more
- with no spacing in between them. It is ambiguous if it should be a heading or an
hr. Currently it treats it as a heading.
