The ustar format only has room for 11 (or 12, depending on

It appears that this blob cannot be read when sizeof(unsigned long) == 4.
This happens to break the t5000 test on Windows, where that comparison
holds true.
The problem occurs in parse_sha1_header_extended(), where the
calculation of the size in the object header overflows our 32-bit
unsigned long.
