PTAL. The way gopls ran 1.19's gofmt, it shifted quite a bit of whitespace in doc.go, which I think we want anyway. To ease your review, ignore whitespace changes: https://github.com/rogpeppe/go-internal/pull/168/files?w=1 |

They used args[0], which is the first argument to the command, rather than the command name itself: > gofumpt foo.go FAIL: [...] use 'exec foo.go' rather than 'foo.go' (because RequireExplicitExec is enabled) I believe I introduced this regression when refactoring the pull request due to Roger's review, as I moved the code out of TestMain, where args[0] was still the name of the command to be run. Note that I can't easily add a regression test here, because the testscript command being used in the tests is not a top-level command run as a separate process, so it does not produce stdout nor stderr. The change seems easy enough to review manually, and our tests don't strictly check all error messages anyway. While here, remove the unnecessary use of -verbose.
