I am not sure this is possible. clang-tidy assumes the code is already
formatted, we cannot assume that in clang-format. This pass runs before the
formatter pass, so basing the behavior on line count would lead to different
behavior across runs. For example:
Assuming we can set this option to 2 lines and we have the following code:
```
if (condition)
very_long_line_that_will_wrap(arg, arg, arg ,arg)
```
first run:
```
if (condition)
very_long_line_that_will_wrap(
arg, arg, arg ,arg)
```
second run:
```
if (condition) {
very_long_line_that_will_wrap(
arg, arg, arg ,arg)}
}
```
Likely is indeed vague by design. We "guess" that it will wrap in the formatter
pass based on the current column value. See Format.cpp @ 1707. What might
happen is that the line is incorrectly indentented and the wrapping never
actually happens.
