commit -S: avoid invalid pointer with empty message
While it is not recommended, fsck.c says: Not having a body is not a crime [...] ... which means that we cannot assume that the commit buffer contains an empty line to separate header from body. A commit object with only a header without any body, not even without a blank line after the header, is valid. So let's tread carefully here. strstr("\n\n") may find nothing and return NULL.
