swift-format#883 fixed outputting incorrect line numbers, but introduced a performance regression. swift-format#901 improved this back to around the original, but had to be reverted as it introduced a an issue due to counting codepoints rather than characters. Introduce a similar optimization again, but only for the first portion of the string (prior to the last newline). Fixes swift-format#894 again.
