How does `tokenize` separate `SourceLine`s?

The function `tokenize` outputs an array of `SourceLine`s. Is it guaranteed that if i provide it with `Text` with some multiline code, every line's tokens will be mapped to one `SourceLine` without any formatting/line changing behaviour?

For example, if I had this single line of oddly written piece of C code:
```c
int do_something() { call_a_function(); int some_number = 3; return 123; }
```
Would very token (e.g. `int`, `do_something`, `()`, `{`, `call_a_function` ...) will end up on the same `SourceLine` with every token in sequence?
