Adding a ReST block immediately after the module docstring breaks the generated .rst file #473
Description
Bug
It appears that both module docstring and ReST blocks are stripped of blank lines at the beginning and end.
Thus the example from https://sphinx-gallery.github.io/syntax.html
"""
This is my example script
=========================
This example doesn't do much, it just makes a simple plot
"""
###############################################################################
# This is a section header
# ------------------------
would result in an .rst file with
This example doesn't do much, it just makes a simple plot
This is a section header
------------------------
resulting in incorrect rendering of the section due to a missing line before it. A similar effect happens if you have just plain text paragraphs: They will be joined.
This appears to be a common pitfall:
matplotlib/matplotlib#13911
matplotlib/matplotlib#13950
Proposed fix
Probably the correct fix would be to always add a blank line after the module docstring text in the generated .rst file.
