* do *not* check the terminal size after each line processing, 

only if we got a SIGWINCH -> interactive use speed-up on the
  slower boxen (slowness courtesy of otto@obsd)
* ^L (redraw line) now (always) checks window size; use this
  instead if required while editing the prompt; changes to the
  variables will still be propagated after the line is entered
