[gedit-list] Display margins at multiple columns

[Drew Schmidt <schmidt math utk edu>]

Hi,

Is it possible to display margins at multiple columns?  For instance, if 
I wanted to display the "right margin" at both columns 6 and 72, is this 
possible?  I'm not worried about text wrapping with either of these 
margins; I just really need them displayed.

This doesn't necessarily have to be universal.  If there is a way to do 
it for just one language (say, Fortran), then that would be perfect.  
But I'll take whatever I can get.

Thanks
