[Debian-med-packaging] Bug#955056: workaround Re: snakemake: FTBFS with Sphinx 2.4: AttributeError: 'member_descriptor' object has no attribute 'expandtabs'

[Rebecca N. Palmer]

An upstream comment says common.py:lazy_property is the problem item, 
and excluding that from the documentation does make Sphinx succeed (I 
haven't tested a whole build):

--- snakemake-5.10.0.orig/docs/conf.py

----------------------------------------------


This is obviously not an ideal fix, but it's an internal class with 
little documentation to begin with:
