Oh, we don't disagree that much then. After all, the help option is the
meat of the comment above. Bringing up the alternative syntax for the
prompt was just a suggestion.

Are you opposed to that second solution?

Yes, that is nice. Did I say, I like the UI over all?

I think showing reviewed-by seperately is good nonetheless, as it might
give an increased awareness to the existence of that line.

In the xserver, no patch is comitted, that doesn't has an explicit
reviewed-by line. That is actually a good thing in my opinion.

That's just sad. At least there are more Reviewed-By then Reported-By. 
I don't think this actually represents reality of the
development process.

Sorry, I didn't look at the use of that. What about  

$bool = (1 - !!$bool) 

then? (if $bool is always 1 or 0, you can drop the double negation in
front of it)
