clang tmp.c -dependency-dot output.dot
# clang-14: warning: argument unused during compilation: '-dependency-dot output.dot' [-Wunused-command-line-argument]
```
When an unused argument is recognized to be one that requires `-Xclang`, it would be helpful to add a note (separately or in the same diagnostic) saying something like `did you mean to use '-Xclang -dependency-dot -Xclang output.dot?`
