[Feature Request] Option to "collapse" multiline strings

[RivenSkaye]

Many languages offer some form of spreading a string over multiple lines. Some using triple quotes (Python, C#, Toml, ...), others with special indicators (Rust's r#""#, C#'s @"", PHP's here- and nowdoc syntax, ...), and others do it based on specific quoting characters (JS/TS with `````) or with adding backslashes at the end of a line. Or SQL, which is valid without newlines but much more readable when using them.

Usually strings are spread across multiple lines to keep code more readable, or to prefer visual newlines over backslash escapes. It'd be nice to have a per-language option to "collapse" multiline strings in code to be counted as a single line. Alternatively (or additionally) a global flag to count it would be great as well.
