Commentary
When च (1. वा 2. ह 3. अह and 4. एव -- न चवाहाहैवयुक्ते 8.1.24) are elided the first verb optionally retains its accent.
Thus with च लोपः - शुक्ला व्रीहयो भ꣡वन्ति or भ॒व॒न्ति॒, श्वेता गा आज्याय दुहन्ति ॥ Here भवन्ति optionally may either lose or retain its accent. So also when वा is elided, as :- व्रीहिभिर्य꣡जते or य॒जे॒त॒, यवैर्य॒जे॒त॒ ॥ So also with the remaining.
