The reason it doesn't work is because the number of repitions is limited
to 32767 (#x7fff).  Obviously that should be documented in the manual.

As to the error message itself, there isn't really a way to distinguish
between incomplete and invalid input, so the only thing I can see to do
is to change the message to [incomplete or invalid input].
