Misleading comment

[maeb]

The following comment:

gowarc/warcfile.go

Line 526 in 614c93d

// WarcRecord will always be nil if error is returned.

seems to be inaccurate because

gowarc/warcfile.go

Line 540 in 614c93d

wf.currentRecord, recordOffset, validation, err = wf.warcReader.Unmarshal(wf.bufferedReader)

leads to

gowarc/unmarshaler.go

Lines 196 to 202 in 614c93d

	err = record.parseBlock(bufio.NewReader(content), validation)
	if err != nil {
	return record, offset, validation, err
	}
	err = record.ValidateDigest(validation)
	return record, offset, validation, err

which returns a warcRecord which is not nil on error.
