Subject: views: blob: render empty blobs specially

Empty (zero-length) blobs are currently rendered by 'pygments'
misleadingly as a single empty line, or, when 'pygments' is unavailable,
as "nothingness" preceding a horizontal rule. In either case, it is
somewhat difficult to glean concrete information about the blob.

Address this by instead rendering summary information about the blob: in
particular, its classification ("empty") and its size ("0 bytes"). This
is analogous to the summary information rendered for binary blobs
("binary" and size).
