Rob Pike c226f6432d strconv: pre-allocate in appendQuotedWith ... The byte-at-a-time allocation done quoting strings in appendQuotedWith grows the output incrementally, which is poor behavior for very large strings. An easy fix is to make sure the buffer has enough room at least for an unquoted string. Add a benchmark with a megabyte of non-ASCII data. Before: 39 allocations. After: 7 allocations. We could do better by doing a lot more work but this seems like a big result for little effort. Fixes #31472.
