Description

Originally reported in pypa/warehouse#4341.

It looks like long_description is full of Windows-style carriage-return characters (^M) which seem to have confused twine/pkginfo about what is and what isn't part of long_description.

My project at PyPI is at: https://pypi.org/project/gff3tool/1.4.2.

Libraries used:

wheel==0.31.1
setuptools==39.1.0
twine==1.11.0

Research direction

Reproduce the Windows behavior using the listed wheel, setuptools, and twine versions, then trace how carriage returns in long_description affect Description-Content-Type metadata. Compare the generated package metadata with the expected PyPI behavior for gff3tool 1.4.2; done means the field is set correctly on Windows.
