The direct answer to your question is to use the 'columns' option,
like so:
echo printf("%." . columns& . "s", longline)
or
echo printf("%.*s", columns&, longline)
I am curious, though, about your comment about having to use q to
quit the echo message. I only ever see "Press ENTER or type command
to continue" after executing your echo.
