Some how I don't see guys like Yoda and Mace Windu tacitly keeping it to themselves. They make it very clear that such attatchment is a danger, not something to be played around with or taken lightly. The idea that they would know about it and just let it slide it completely and totally out of character for both of them.

I think it fits with what we know of Yoda. Yoda manages his students by counsel and advice, but he does not take action against his students when he thinks they are doing something wrong. He and Obi-wan "knew" that if Luke went to Cloud City, he'd fail; but he did nothing to actually stop Luke, no matter how disastrous the failure would have been. Likewise, Yoda counseled Anakin that attachment led to the Dark Side (somehow); to openly accuse Anakin of having an illicit marriage would have led to the guy's expulsion from the Jedi Order, and thus constitute de facto intervention. I can't say for sure that Yoda knew, but I'm pretty sure that if he knew, he wouldn't go squealing to the Jedi Council.

As for Mace Windu, I was unaware he had a character.

Even Obi-Wan seems to know be 100%, he just suspects. When he goes to Padme to warn her about Anakin he asks her if the baby is Anakin's. Had he know they were married, or even together, that question would not have made any sense. He suspected it, but didn't know for sure.

The question makes perfect sense. People don't just ask questions to elicit information, they also do it to provide information in a circumlocutious manner, or to influence behavior. I think we're so used to Lucasian dialog--characters marching onstage and announcing their feelings or intentions--that we don't notice subtlety when it is achieved.
