It no longer checks "the first few lines" but can read a lot more, so the
comment that precedes this block is now invalid.

Also we are rather old fashioned and we never say "until [ ... ]" anywhere
in our shell scripts.

	$ git grep -e until -- '*.sh'

Personally to me this is a borderline "Meh", in the sense that I wouldn't
bother to waste too much effort rejecting it, as I do not see downsides
other than these minor points.

Thanks.
