Now that you've said that, I realize that the behavior I am after is actually a
vim enhancement.  When I turn on vi-compatibility mode, the cursor gets stuck
when trying to repeat a t/T search just as it does in readline.  I should have
checked that before I posted the report--I guess I've been running vim too many
years!

I don't know if you are willing to move beyond POSIX, but this changes a no-op
command into something more intuitive (te;; == 3te, rather than te;; == te).
Don't GNU programs generally extend POSIX where there is utility in it?  If
not, I understand and thank you for your consideration.
