 Title: #5198: tox.ini: Extend max-line-length from 80 to 88+
Action: opened

PR body:
"""
Change tox.ini's 80c character limit to 88.
- 88 is the limit for a font size of 14 on a FHD (1920x1200) screen
  with two editors side-by-side.
- A too-high number can become an issue for potential contributors
  with eyesight problems. So we want to avoid that.
