We don't use this test idiom in other places, it's OK to just use "$1" =
"!". I think we're past whatever portability concern made that popular
in some older shell code in the wild.

Slightly off topic but if anyone is interested in the history of this test idiom and why it is no longer needed there is a good article at https://www.vidarholen.net/contents/blog/?p=1035
