Steps to reproduce

(How can someone else make/see it happen)
Use git repo to store configuration:

# ssh into hassio:
cd /config
git init
git add .
git commit -m "initial commit"

Then, make some changes:

cd /config
# change something:
vi configuration.yaml 

# This shows bad colours:
git diff

Proposed changes

(If you have a proposed change, workaround or fix,
describe the rationale behind it)

Following @jkeljo advice in home-assistant/supervisor#343, installing a more feature version of less fixes it: apk --no-cache add less
