optimize representation of empty lines in <li> and <blockquote> content #170
Description
In <li>, empty lines still get indenting spaces (spaces replaced with · in output):
from markdownify import markdownify as md
html = """
<ul>
<li>
<p>1</p>
<p>2</p>
</li>
</ul>
"""
print(md(html))
# *·1
# ·· <-- HERE
# ··2Similarly in <blockquote> empty lines get trailing marker spaces:
from markdownify import markdownify as md
html = """
<blockquote>
<p>1</p>
<p>2</p>
</blockquote>
"""
print(md(html))
# >·1
# >· <-- HERE
# >·2These empty spaces are unnecessary and can be omitted for brevity.
