I can't think up any case when match is not null while match[1] is falsy here, as the first group does not use a quantifier that can end up in an empty string. So I suppose the match[2] is intended to prevent arguments like n=. However, I may miss something obvious.

I think you’re right, but it might be even simpler to change * to + in the regex (unless I’m missing something)?

I agree with @addaleax, either we allow passing foo= as a key that's equal an empty value, or we disallow it at which point it's better to match + directly.

@addaleax, @benjamingr PTL, if I've understood you correctly)

BTW, why [\s\S]? Do we have or allow \n in the CLI arguments?

I would guess it does not actually matter. It might be nice for scripts to be able to set string parameters to whatever they want, including text containing newlines… ¯\_(ツ)_/¯

Oops, I goofed and landed this without a CI run (it got batched in with a couple of other ones I was working on landing). Looks like the change breaks test/sequential/test-benchmark.http.js. Revert PR is in.

@jasnell Sorry, I had to run the CI. Trying to understand how to fix.

No worries, I should have double checked. I had it grouped in with a set of others that I was landing all together and missed it entirely.

It seems we do have cases as key= as valid CLI params:

Trying to grep another possible cases...

CI fails only on Windows possibly with ref to #12475

Dear reviewers, could you re-review?

Post mortem on the original botched landing: I believe that I simply had ended up putting this in the wrong list when I was organizing which PRs to land and which needed more work. This one obviously should have gone in the latter list. Since it was a change to benchmarks and we've only recently added benchmark tests to our CI set, I haven't got myself in the habit yet of running make test on benchmark: PRs. I ran make lint and went with it. Sorry all.

Marking as dont-land as I think this depends on #7094, which was semver-major. Correct me if I'm wrong.
