> The issue here as I see it is that we parse "home" as an identifier, but not "/home". The latter currently needs to be quoted in the WiredTiger parser because it doesn't start with [A-Za-z0-9_]. I can change that fairly easily, and this seems like a common case.

I agree we should make this change.

Also, I don't see any place where we document the syntax of our configuration strings, that is, how do users know what needs quoting and what doesn't – am I just missing it?
