According to the 4.3BSD manual, termcap(5):

	sg  num  Number of garbage chars left by so or se (default 0)

According to SVID Vol 2.:

	magic_cookie-glitch  xmc  sg  # of blank characters left by smso or
								    rmso


Now, the question I have is what is the difference between not defining
these and defining them to be 0?

From my standpoint, they mean the same thing. If a terminal has a 0-width
magic cookie, that means it puts 0 extra characters when it switches to
standout mode. If it doesn't have a magic cookie, that means it doesn't
put out any extra characters when it switches to standout mode.

Even if I was educated in the South, I'm pretty sure that "0" and "not any"
mean the same thing in this case.

Can anyone help out with this?
