Gomark handles line breaks differently than traditional markdown renderers.

Memos displays correctly; however, when I use other rendering plugins after retrieving data via the open API, discrepancies arise. Here are some examples:

1. Handling of line breaks:
   If there are two line breaks, Memos renders a blank line, while most other renderers ignore this blank line. For example:

test

test

Rendering results.
test

test

Gomark rendering results
The GitHub markdown renderer ignores empty lines, so they won't display, but there will be an extra line in memos as follow screenshot.

2. blockquote
   In the following example, there is only one blockquote, while gomark also renders a separate paragraph.

> test
test

Rendering results.

test
test
