Well, you are supposed to get the attributes for sequential columns:
:echo synconcealed(1, 1)
:echo synconcealed(1, 2)
:echo synconcealed(1, 3)
Then it should work. If you get it for the same column, because of how
syncing works, it starts all over again at the start of the line and
keeps incrementing the ID counter.
This is indeed very ridgid and easy to get confused. Perhaps it would
work when we reset the counter at the start of the line? This assumes
you won't compare the number between two lines, which mostly makes
sense. It is possible that an item continues from the end of one line
to the next though. Oh, we can reset only when syncing, that should
always work better.
