This off-by-one error was caused by a slight difference between the pos argument to lfs_index_find and lfs_index_extend. When pos is on a block boundary, lfs_index_extend expects block to point before pos, as it would when writing a file linearly. But when seeking to that pos, the lfs_index_find to warm things up just supplies the block it expects pos to be in. Fixed the off-by-one error and added a test case for several of these cold seek+writes.
