Subject: Reflowing the grid in-place involved way too much memmove() for a big
 performance cost with a large history. Instead change back to using a second
 grid and copying modified lines over which is much faster (this doesn't
 revert to the old code however which didn't support UTF-8 properly). GitHub
 issue 1249.
