patch_parse: reject empty path names When parsing patch headers, we currently accept empty path names just fine, e.g. a line "--- \n" would be parsed as the empty filename. This is not a valid patch format and may cause `NULL` pointer accesses at a later place as `git_buf_detach` will return `NULL` in that case. Reject such patches as malformed with a nice error message.
