Using the default dokuwiki template, and Release 2018-04-22b "Greebo"
An empty line (just a newline character)
before a line with a sequence of four (or more) dashes
expands out to an <hr> (Horizontal rule).
This is the normal/documented behavior.
A line with just a single space (followed by a newline)
prevents a sequence of four (or more) dashes on the next line
from expanding out to an <hr> (Horizontal rule).
Is this expected? A feature? A bug?
