Including.
As for the hard limit, pretty much.

"Legitimately"? I very much doubt it. (Only half joking.)

I would consider anything more than four indents a code smell. That is, 
four is unexceptional; five would make me look over the code to see if it 
could be refactored; six would make me look at it *carefully*; eight 
would have me questioning my own sanity. I wouldn't give a hard limit 
beyond which I would "never" go beyond, but I find it difficult to 
imagine what drugs I'd need to be on to go beyond eight.
