New Revision: 20489

Log:
And on the sixth day, God gave us the <= operand, which makes the loop
"for (i = 1; i < num + 1; i++)" look like "for (i = 1; i <= num; i++)".
Programmers worldwide rejoiced and used the operand, e.g. in the thread
"[PATCH] remove ugliness in cel_filters.c", and He saw that it was good.
