This has is a nice-to-have for me. Frequently I want to run a specific test, and end up digging through output to be able to copy-paste the run line. This uses TIP lines to inject the command into the file when using AUTOUPDATE. Note, one of the reasons I want this is because "bazel test //toolchain/testing:file_test --test_output=all" has been regularly exceeding bazel's output limit for me (workaround is either opening the output file or specifying an obscure output limit flag), making it a little harder for me to get the commands. However, frequently I'm adding a file and want to iterate on it, so that's really the use case I have in mind here.
