Subject: [PATCH] Save the day fix for Google Bad Request (400). This will pull
 text till a query limit (5k) and will require multiple presses to "Start +
 Apply" if some text to be translated is too long. In next revision may do
 Take(1) till max(10, payload limit) for enumerator and let it do its thing.
 However another bigger issue remains: a single source can be bigger than 5k
 limit and splitting it up may degrade the nmt translation context causing
 worse translation on Google's end. This needs some research on proper
 splitting.
