I "fixed" an issue in #840 only to realize, I left it broken in another way. Sorry for that. Anyway, here's the actual fix (I hope).

I frankly still don't understand, why end_col = end_col - 1 is needed in the first place, as it breaks the expected behaviour of is_in_range(). I assume it's a quirk specific to the location where the function was being called from, so I moved it there.

Because treesitter range is end-exclusive. For example there are cases like (last_row+1, 0) is the end position to mean it's till the end of the file. If you don't calibrate it well, it will throw out of range error.

I think the safest fix is to copy the functions from neovim upstream for now.
