 * Definition of the results of comparisons for files and for lines 
 * within files. 
 * 
 * These need to be globally declared so that the UI code in windiff.c can 
 * map states to the colour scheme (to correctly highlight changed lines). 
 * 
 * They apply to files (compitem_getstate() ) and to sections in the 
 * composite list (section_getstate). All lines within a section have the 
 * same state. The UI code will use the view_getstate() function to find the 
 * state for a given line on the screen.
