It may depend on your discipline, but I've noticed that faculty candidates for Computer Science that interview at my university tend to list their job talks on their CVs as invited talks.

Therefore, being cagey about where you're interviewing or trying to obfuscate it would be counter-intuitive.  You're probably already leaving a pretty obvious trail from your job search, people in your field probably know others in your field and communicate with them, and it wouldn't be difficult information for anyone to find out, so it would seem like being up front and honest about it would be the best path?

Should I tell other interviewers where else I've interviewed?
I'm wondering if the need to alter the indentation of code to adjust the nesting has any adverse effects on merging changes in a system like SVN.

This is a really open ended question. I'm sort of fishing for information/anecdotes here.

Edit: Thanks all! I'd accept an answer but which one? I up moded them all.
