Partial cleanup of find - Remove unnecessary headers - dump_node is not used anywhere - exec_buf is unused - Replace SUCCESS with 1 and simplify code accordingly - a==0 -> !a - Simplify an incremation pattern using pre-increments - Add static keyword to functions - Make error messages print to stderr
