r.colors: Bug and Fix

[Michael Schulz]

Dear List !

When trying to change the colortable of a raster map via r.colors and 
rules-File or interactively, the program did not recognize the "end" 
command of the rules-File. 

This bug is reported for r.colors in the list 
of reported bugs for GRASS 5 
(http://www.geog.uni-hannover.de/grass/grass5/known_bugs_aug99.txt).
I don´t know if this is a real fix for it, but it is a workaround:

Replace in $GISBASE/src/raster/r.colors/cmd/rules.c:

line 163: if (strcmp(buf, "end") == 0) return 0;

with:     if (strncmp(buf, "end",3) == 0) return 0; 

BTW: The same is applicable for line 165, the help command !

Cheers, 

Michael
