Perfect! I just tested, it seems like I can use synstack() without mucking around with adjusting column number. Here's what I'm doing to get a string to compare to "Comment":

let curHLgroup = synIDtrans(get(synstack(line('.'), col('.')),-1))

So this leads to the question: is synID()'s behavior intentional, since synstack() is able to process past the end of the line?

If so, perhaps a help note about the behavior of synID, and a link to synstack, would be useful.
