> The docstring for compile-command says: "This variable is safe as a

Thanks for the bug report.

I think the main risk occurs when the user has customized
compilation-read-command to nil, because then M-x compile does not issue
a prompt.  So, I've changed the predicate to consider compile-command
unsafe if compilation-read-command is nil.

We could be more aggressive and always consider compilation-command
unsafe, but I'm not sure that's warranted.  After all, there is the risk
that your makefile is malicious, anyway.
