Another stammerer here (one of crazyhorse's "rare females"), but posting anonymously as I don't want to be one on the internet - damnit, that's the whole point of text communication. Came to this late via the podcast.
I'm a mild, moderate or severe stammerer depending on the context. I don't have any problem with people saying the word I'm stuck on (finishing the whole sentence is going a bit far) as long as they get it absolutely correct. For instance, I work with someone whose name I cannot say without significant problems. If I'm talking to someone else about her and it's clear whom I mean it would make me quite happy if they just said the damn woman's name (I'd also like her to change it to something I can say). In contrast to people who've said they feel it shows a lack of respect for what they are going to say, I feel in some situations it can show respect for the conversation and that the other speaker wants to go on with it. But someone finishing what I'm saying wrongly can make my fluency much worse. I agree that there is no reason why you shouldn't ask your student what he feels about you completing words for him, probably as part of a larger discussion, possibly by email, about how he'd like to be treated.
Signs of impatience, as several people have said, are usually counterproductive, though sometimes if they make me angry I can get pretty fluent. Usually not in a helpful way though.
bwg said "I just told him as friendly as possible to take his time". I realise this was meant kindly and seems to have worked for the person bwg was talking to, but it winds me up something chronic. It implies - to me - that the person I'm talking to is assuming that I haven't thought of doing that for myself, and that they think it's a simple problem that could be solved if I "just took my time". Grr.
As for the other specific questions. When I'm stammering I may be thinking "gods, not again,", trying to think of a word starting with S that replaces the word I can't say, or I may be thinking what to have for tea. To some extent I think it's a non-question - like asking what someone's thinking as they limp, for instance. For those of us who stammer it's often so much a part of our lives that we don't think anything particular about it when it happens. The only time when I do think something pretty standard is when I am stammering for the first time with someone I haven't stammered with before - I know it can look pretty odd (I've met my fair share of stammerers too) so I'll be worrying about that.
As for what it feels like, to me it feels as if the word is stuck in my throat and that I'm on a repetition loop, knowing that at some point something will click, possibly after some magic number of repetitions, and I'll be able to say it, or find some way to get round it (ranging from word substitution to leaving the room). I'm interested in aeschenkarnos's suggestion about OCD - I've wondered about this myself, particularly after reading Amy Wilensky's memoir Passing for Normal about Tourette's and OCD, and would value ikkyu2's take on this.
The only other thing it might be useful to say is that you will know when your student is overtly stammering, but you won't know when he's covering it up and perhaps not quite saying what he wants to, or not speaking at all not because he has nothing to say but because he can't say anything at all. You may want to talk to him about ways he could let you know if there's something he wants to contribute but needs formal recognition to start (such as putting his hand up and you asking him what he has to say - informal group discussions can be hell for stammerers). And let him know clearly if you will be assessing verbal contributions (I'm still slightly bitter about a class years ago in which I said nothing, not knowing that it mattered). I realise this borders on special treatment, but unlike crazyhorse I don't see that that's a problem. But then I like to get my say one way or another - even if anonymously.
Oh yeah - sorry, I'm ranting now (yes, I do this verbally too) - don't give into the temptation of telling your student, in an excited way, about any "miracle cures" you hear about. He'll have come across them too if he's interested.
