Cop name

Layout/LineLength

Is your feature request related to a problem?

Layout/LineLength is one of the cops that have the most different causes, to name some:

• SQL statements
• CLI commands
• URLs
• Object tree access
• RegExp (list of keywords)
• Rescue (network) classes
• Call chains

By contrast, the manual is disproportionately helpful in exemplifying and remedying the causes:

Describe the solution you'd like

Initial thought is to split the cop into different cops (now there is something T-1000 didn't think of...), addressing the usual suspects with specific individual recommendations.

Code examples

# Some brief illustrative cop message examples (for now):

- "Write SQL statement as HEREDOC"
- "Piece together the CLI statement as an array"
- "Scan for words and intersect with array"

Describe alternatives you've considered

Putting long statements in YAML file it not always viable as it might cause a lot of buffer switching.
