Pulses of 2 or less ticks have no effect on dispensers
Repro Steps:
1. Create a 1 or 2 tick clock or pulse limiter, such as a loop of 2 Repeaters each on 2 tick setting. (see attached image)
2. Connect it to a dispenser and place some items in it.
3. Activate the clock/pulse limiter.
Result: No item is dispensed.
Expected Result: Any length pulse will activate the dispenser (which was the behavior prior to Snapshot 13w01a)

I also found this. I even tried activating the dispenser with a button and had no luck. I am using 13w01b.
The dispenser WILL activate with the first pulse, but it does not deactivate fast enough to be triggered by the second pulse.
I'm attaching a screenshot of a configuration that works just fine without any sacrifice in speed.
Works as if it were only hooked up to the pulsing repeaters.
MAY TAKE A FEW TRIES AT FIRST! Just keep switching the delay on the repeater behind the dispenser.
Using a clock that uses a 1 tick pulser from torches will cause a dispenser not to fire. When using a traditional 2 repeater method does work for me.
This seems to be fixed in 13w10b. So dispensers and droppers both get triggered by 1 tick pulses and 1 tick clocks (2 ticks cycle), however a comparator clock only triggers them once if they are placed to close to the output of the comparator. I haven't tested good enough, but it seems that the dropper or dispenser has to be more than 2 blocks away from the block in front of comparator to get triggered multiple times.
(See MC-11189)
Resolving as fixed, with MC-11189 detailing the new problem.
Power the dispenser and it will trigger with the pulse. it was that way before the snapshot in 1.4.6 so i don't know if its a bug or not
