  1. grep: add -R alias for -r 

    * On *BSD, there's no difference between grep -r and grep -R, so adding -R in this version allows for greater compatibility
* Also add missing validation: $pattern can be undefined when shifting off ARGV, and it's a fatal error if we get no patterns (found with "perl grep -r")
