Marking more than 1000 email as read fails

[jzuken]

Could you please implement marking more that a thousand emails as read?

I had 2067 unread emails with the target label and run the tool with the '-mark' argument, which resulted in the following message:

failed to batch-delete label UNREAD from 2067 messages: googleapi: Error 400: Number of ids cannot exceed 1000, invalidArgument

The full command in this case was go run main.go -l alerts -mark -html -refs -compact.

Good catch! Indeed that is just not implemented yet.

This would be a simple change that requires batching msgIds by 1k instead of passing them all together in

scholar-alert-digest/gmailutils/gmail.go

Lines 218 to 220 in cc25621

	func ModifyMsgsDelLabel(srv *gmail.Service, user string, messages []*gmail.Message, label string) {
	var msgIds []string
	for _, msg := range messages {

before calling BatchModify API.
