Would be curious to see CITGM results as I could see this impacting test suites. (But maybe not?)

@addaleax about this being semver-major: we actually have the following in our docs:

The output of util.inspect may change at any time and should not be depended upon programmatically.

So I personally do not think this is semver-major. When added, it was somewhat meant for changes like these as far as I can tell.

@BridgeAR Yes, this is definitely in the “erring on the side of caution” category. I know that people shouldn’t depend on it, but I’m not sure this change is trivial enough to have a reasonable expectation that it doesn’t break people’s code.

If there is a good reason for this not being semver-major (as in, a significant advantage for us), we can remove the label.

CITGM: https://ci.nodejs.org/view/Node.js-citgm/job/citgm-smoker/1418/

@BridgeAR
util: wrap error in brackets without stack
13a3ae3 
This aligns the visualization of an error with no stack traces set
to zero just as it is done in case the error has no stack trace.
@BridgeAR
util: remove erroneous whitespace
5639463 
When inspecting nested objects some times a whitespace was added at
the end of a line. This fixes this erroneous space.

Besides that the `breakLength` was not followed if a single property
was longer than the breakLength. It will now break a single property
into the key and value in such cases.
@BridgeAR
util: fix inspected stack indentation
96b303c 
Error stacks and multiline error messages were not correct indented.
This is fixed by this patch.
@BridgeAR
util: improve error inspection
9c1d559 
When inspecting errors with extra properties while setting the
compact option to false, it will now return:

[Error: foo] {
    at repl:1:5
    at Script.runInThisContext (vm.js:89:20)
  bla: true
}

Instead of:

Error: foo
    at repl:1:5
    at Script.runInThisContext (vm.js:91:20) {
  bla: true
}

Rebased due to conflicts.

New CI https://ci.nodejs.org/job/node-test-pull-request/14988/

Since the conflicts required some more work, PTAL.

@addaleax one main benefit would be easier backports.

@addaleax I still think it would be best not to have this as semver-major.

@BridgeAR If you feel strongly about this, you can remove the label… I don’t think this is something we’d want to backport to an LTS line, though
