Given the current implementation, APR_BUCKET_IS_METADATA(e) implies that
e->length is 0 and apr_bucket_read(e) returns "".

Skipping the read call if it's a metadata is nothing more than an
optimization in this case.  (You should throw in the check for len != 0,
that's almost as good an optimization.)  My feelings aren't hurt one way
or the other by having this in.
