write: exact allocation for newLinesIndices

Minor change which makes the function slightly slower, but use much less
memory / allocations. A benchmark on a medium sized repo showed this
function was 4% slower, but 60% less memory allocated. This is a minor
part of indexing so is likely not noticeable. However, was a quick
win.

Can also update the algorithm to use bytes.IndexByte. However, that code
is more tricky and this function doesn't contribute much time indexing.
