[LAU] jackd --clocksource long option broken?

Hello, just been fighting with some jackd starting problems, and figured out that: jackd --clocksource hpet <snip> produces an: Unknown option character error and fails to start, while the short option works: jackd -c hpet <snip> JACK compiled with System V SHM support. loading driver .. apparent rate = 41000 creating alsa driver ... hw:HAMMERFALL|hw:HAMMERFALL|1024|2|41000|0|0|nomon|swmeter|-|32bit configuring for 41000Hz, period = 1024 frames (25.0 ms), buffer = 2 periods ..... So nothing dramatic here, but if this happens not to be an arch linux specific issue, maybe the manual page can be fixed with 0.126 or whatever verion will follow. Just felt like metioning it and maybe somebody can confirm this behaviour. Or not.
