For loop bug

Chronos

Found a strange "for loop" bug when going from i=0 to -1 with a step -1.

// as expected, prints nothing
for i=0 to 0 step -1 loop
	print(i, "\n")
repeat
print("Start B\n")
// very inconsistently, prints both 0 and -1
for i=0 to -1 step -1 loop
	print(i, "\n")
repeat

loop
update()
repeat

i don't think it's a bug as it goes until -1 -1 so actually -2
it does endvalue -1

But it is indeed weird with the 1st one. it probably does some calulcations with start value and end value. And having both the same might have an influence. (like it checks if startval and endval are the same if so do nothing) I try to not use for loops with negative steps. If i need it i use a while

But a similar for loop going from i=0 to 1 prints 0 and not 1.

print("Start C\n")
// prints both 0 and 1
for i=0 to 1 loop
	print(i, "\n")
repeat

@Chronos it starts on 0 if you had 10 it would be 9

I know, I'm stating that to demonstrate the inconsistency in the loops' behaviors. The problem loop is from 0 to -1 including -1.
