Did you know that NIS netgroup syntax is somewhat relaxed about triples being comma-separated?

When creating a netgroup, its source file syntax allow both forms:

# machines (desktop-1,-,business.domain), (desktop-2,-,business.domain), (desktop-3,-,buinsess.domain)

or

# machines (desktop-1,-,business.domain)  (desktop-2,-,business.domain)  (desktop-3,-,buinsess.domain)

I was trying to figure out if one could have a definite advantage over the other in all cases, but I think not, as the matter could be subject to specific requirements, that is, depend on requirements.
That is, the comma may or may be not useful depending on the case at hands.

Regards.
