[issue15266] Perform the same checks as PyPI for Description field

[Wichert Akkerman]

Wichert Akkerman added the comment:

Éric is not quite correct: I currently have a package where "python setup.py check" does not show any error, but PyPI still refuses to format my long description. Likewise "python setup.py --long-description | rst2html-2.7.py > /dev/null" also does not reveal any errors or warnings, so I am at a completely loss as to why PyPI refuses to format my documentation.
