Restrict comments to 100 characters

This is a rule I try enforce in PR but it's a bit of a hassle, this will
give a lint warning when it happens resulting in:

- Yellow underline in supported editors when eslint is installed
- Compilation will succeed since it's a warning not an error
- CI will fail as it does not allow lint warnings

Special case comments are ignored which includes @vt comments, table
comments and commented out code.
