I have a func:

   echo printf("%.10s", longline)

But if longline is longer than screen line, then it will be broken down
into several lines, I have to use q to quit the echo message, that's
not what I want. So question is, how to get the width of screen line, so
I can use:

   sline = screenline
   echo printf("%." . sline . "s", longline)

to truncate the longline to fit the screen?
