Enable raising lint warnings for mulitple lines at once

Browse source 
Summary:
We have a lint rule checking if some string is too long.
This string can span multiple lines.
If we report a warning at the first line then it is muted if the first line wasn't modified.
We need to say that this whole block is wrong and report it when at least one line from the block was modified.

Test Plan: Changed a lint rule to call `raiseLintAtLines()` and verified that the warning is reported even if the changed line isn't first.
