[power-pro] for each line issue

[sgp]

Powerpro 4.9L, standard configuration. Run this script

for each line in "\r\n\r\n\r\n"
  win.debug(time,line)
endfor

I expected 3 lines of output, I got none. Bug?

If I add some other characters I start getting output:
for each line in "A\r\nB\r\nC\r\n"
  win.debug(time,line)
endfor
