Acked-by: Ian Campbell <ian.campbell@xxxxxxxxxx>

BTW, I noticed that your valid blessing regex here includes "-", which
is not allowed elsewhere, which breaks "./standalone make-flight -f
$branch $branch" for our common branch names meaning the flight name
needs some munging. A minor inconvenience, but if this check were moved
to a centralised helper it could be easily fixed...

Or at least this was once the case, I can't see the problematic check
right now and haven't actually tried this for a while. Perhaps it got
fixed already and I didn't notice?
