[fpc-pascal] Value of runner variable after a for loop

[Andrew Denton]

I would NEVER rely on this in production code. The value of the control
variable of a For loop after execution should never be relied upon. A simple
change in the compiler at some future point could break a lot of your code.

Cheers,

Andy

And unless the compiler (programmer) use an extra variable just to
attain this behaviour, the value after the loop will 3 (i.e. end value
+1).
