I know the "x" option causes the regular expression engine to ignore whitespace, but is there a reason to not just have .*-.* or even just - here?

I thought .*-.* looked a little compressed and this helped it be more obvious, personally, but I don't feel strongly about it (especially with the comment out to the side which makes it pretty obvious 😂) -- we can't do just - because of the :+$ anchoring outside the parenthesis here (we're matching the full "tag" portion of the image references explicitly with this).

Is this safer than mapfile/readarray?

It's more reliable in my experience (and certainly no less safe).
This is an attempt to help codify #162, and make sure that it's correct / mostly automated. I'd love to figure out a clean way to help @docker-library-bot be able to make these kinds of updates automatically, but that's a much larger/more complicated problem.
I'm not 100% sold on it, especially how fiddly and frankly unapproachable my filtering method is.
