help needed for fixing ruby-github-markup test failure

[Pirate Praveen <praveen@onenetbeyond.org>]

Hi team,

I was trying to fix the rc bug #938419 (just changing dependency to 
python3-docutils and changing python2 to python in 
lib/github/markups.rb seems enough) but noticed the build is failing 
and tracker.d.o shows autopkgtest regression.

Full build log 
https://ci.debian.net/data/autopkgtest/unstable/amd64/r/ruby-github-markup/3761802/log.gz

MarkupTest#test_org = 0.11 s = F


Failure:
MarkupTest#test_org 
[/home/pravi/forge/debian/git/ruby-team/ruby-github-markup/test/markup_test.rb:71]:
README.org.html's contents are not html equal to output:

Looked at ruby-org as a potential culprit here, but it was not updated 
during this interval and upstream test pass when changing version to 
0.9.12 in Gemfile to match version in debian.

It started failing from 2019-12-26 and looking at the diff between 
testbed-packages from artifacts.tar.gz it is caused by libedit2

diff --git a/testbed-packages b/second/testbed-packages

Any clues?
