I hoped that no matter what the command string contains that emacs would start it. I suppose `compilation-start' attempts to set default-directory to the cd it sees, but doesn't notice the command itself will create it. A similar thing happens if you've got a hairy shell expression in the cd, (compile "cd ${FOO:-${BAR}};\n echo hi") => emacs error I suppose in this case the expression is more than substitute-env-vars understands. I think if the apparent directory in a command doesn't exist then compilation-start shouldn't try to use it.
