When will this finally get resolved?
1. We cannot reuse ANY documentation written elsewhere, because Bitbucket is the only party that does not respect line breaks in text. Similarly, any documentation written with Bitbucket's poor Markdown implementation is completely rubbish outside Bitbucket.
2. The current implementation of "two spaces make a line break" is unworkable. These extra spaces will break (for example) bash multiline code snippets.
3. Any IDE with a Markdown preview is useless, because the preview does not reflect Bitbucket's faulty Markdown rendering.
