Keep the example commands? I copy-paste from them often

[paschalis-mpeis]

Will do, thanks! Setting up the wrapper now stays under a flag, so I'll reintroduce this example when I rebase the patch.

[paschalis-mpeis]

Forced pushed to rebase and handle this.
llvm-bolt is available only when the --create-wrapper flag is used (as a wrapper).
In that case, the commands are valid and now printed.

Also applied a few more nits.
