For clarification as to why I asked:
Right now, I'm trying my hand at cleaning up the code in sys/scsi/st.c
(thereby generating the questions, however, it's going fairly well, I hope
to submit a patch soon). I figured I'd get used to the style (by
reformatting old code), before attempting to (re)write anything in that
style (as it's not the format I usually write in).

Yeah, and as a fairly recent learner of "C" (1996ish), "Goto considered
harmful" had been pounded into my brain.
Seeing gotos kinda was shocking (for someone who programs in a
function-based fashion), but I figured they might be there for a reason.
