Thanks for the report. I assume you mean the second j, since the examples
below show that.

I forgot how many special cases you have to account for in vi. In this one,
the motion command (`tj') doesn't move the cursor at all, so it's a no-op
when issued individually, but when issued as a motion command with commands
like `c' or `d', it has to consume at least one character. There was
already a special case in there for c/C, so it looks like d/D will need one
as well, and probably y/Y.
