It's currently too easy for someone to bork their shell by doing something like `function test; return 0; end`. That's obviously a silly, contrived, example but the point is that novice users who learn about functions are prone to do something like that without realizing it will bork the shell. Even expert users who know about the `test` builtin might forget that, say, `pwd` is a builtin. This change adds a `--shadow-builtin` flag that must be specified to indicate you know what you're doing. Fixes #3000
