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.
