As with git_diff_blobs, comparing a blob and buffer lacks some context,
so the git_diff_file parameters to the callbacks will be faked a la the
rules for git_diff_blobs().
Passing null for old_blob will be treated as an empty blob (i.e. the
file_cb will be invoked with git_delta_t.GIT_DELTA_ADDED and the diff will be the
entire content of the buffer added). Passing null to the buffer will do
the reverse, with GIT_DELTA_REMOVED and blob content removed.
@param old_blob Blob for old side of diff, or null for empty blob
@param old_as_path Treat old blob as if it had this filename; can be null
@param buffer Raw data for new side of diff, or null for empty
@param buffer_len Length of raw data for new side of diff
@param buffer_as_path Treat buffer as if it had this filename; can be null
@param options Options for diff, or null for default options
@param file_cb Callback for "file"; made once if there is a diff; can be null
@param binary_cb Callback for binary files; can be null
@param hunk_cb Callback for each hunk in diff; can be null
@param line_cb Callback for each line in diff; can be null
@param payload Payload passed to each callback function
@return 0 on success, non-zero callback return value, or error code
Directly run a diff between a blob and a buffer.
