John Baldwin a8b6a13b0a diff: Don't (ab)use sprintf() as a kind of strcat(). ... Previously print_header() used sprintf() of a buffer to itself as a kind of string builder but without checking for overflows. This raised -Wformat-truncation and -Wrestrict warnings in GCC. Instead, just conditionally print the new timestamp fields after the initial strftime()-formatted string. While here, use sizeof(buf) with strftime() rather than a magic number.
