I'm adding:

GetWindowCols

  (GetWindowCols [window_number])

  Returns the number of visible columns in the specified window. If you 
don't
specify a window number then the current window number is used. If the
specified value is invalid this function returns 0.

--------------------------------------------------------------
GetWindowRows

  (GetWindowRows [window_number])

  Returns the number of visible columns in the specified window. If you 
don't
specify a window number then the current window number is used. If the
specified value is invalid this function returns 0.

I'm also adding a third command to get the "Wrap column" setting. So we 
can write a couple of sLisp macros to format using the window width and 
using the wrap column setting. We could even create one set to format 
the selection and another to format the whole file.

Good! Please add the command line option to select the columns.

How did you meassure the time? May be the problem is the communication 
with the editor.

I tried it in my Debian GNU/Linux Sarge box and it worked flawlessly.
