110 is what we enforce in Python code via our existing lint rules, and
120 is what we'd most realistically move the JS codebase to next.
Make supported IDEs and text editors keep a maximum line length of 110
characters for most code files.
I didn't add anything about the following extensions since they had
way too many different styles:
- .txt
- .conf
- .erb (saw tab, 2-spaced, 4-spaced and 8-spaced files around the codebase)
Fixes#3099.
