This could certainly be made clearer. I'm assuming that if someone is doing `wp search-replace orange orange` they're trying to safely test how many replacements will be made. Suggesting `--dry-run` in the hopes they'll adjust their command to `wp search-replace orange apple --dry-run`

Perhaps instead of 'Use --dry-run', (which could imply rerunning the command with that tacked on at the end) it should be a little less forceful, like "See the --dry-run option"
