Line breaks aren't treated specially in attribute, so they can be part of 
both the attribute name and value.  The first equals sign spearates the 
name from the value; further equals signs are part of the value.

In this example, "aa" is the attribute name, and "bb\ncc=dd" is the 
attribute value.  For show_name_value=value, gschem displays

bb
cc=dd

and for show_name_value=name, it consequently displays

aa

You would display anything that follows the first equals sign--an empty 
line, a line containing "aa=bb", and a line containing "cc=dd".
