At least I'm quite sure about this oneâ¦
Previously this was needed because `couch_httpd:etag_maybe/2` was called
there. Its return value contains either a mochiweb response (if the etag
matches), or a `vacc` record (if the etag doesn't match).
Now that we don't call `couch_httpd:etag_maybe/2` there anymore, the
response should always be a `vacc` record, and therefore the case clause should
be obsolete.
