This patch adds the following control flow commands: if <condition> <true-cmd> Execute <true-cmd> if <condition> is non-zero...
Thinking about this point again, and it goes for 'loopif' as well, do we wish to use zero or non-zero? If we ever have something akin to $(command), command's return code should be zero on success. I made an error in the last e-mail saying that this could stay as non-zero if we ever had $(command)-style support.
