Commit Message

grep: -q and -s options reversed

* This grep has the standard meanings of options -s and -q backwards [1]
* -s is to suppress some errors
* -q is to make grep not show matches, and perform a quick search of one match per file
* test1: "perl grep -c yo grep" --> count the matches of "yo"
* test2: "perl grep -cv yo grep"-->  count the lines not matching "yo"
* test3: "perl grep -q perl  grep" --> quiet search for "perl"; exit status 0 indicates Match
* test4: "perl grep -q pascal grep" --> quiet search for "pascal"; exit status 1 indicates NoMatch
* test4: "perl grep -s greg greg" --> silent search for "greg" but the file doesn't exist; exit status 2 indicates Error
* Correct POD manual and usage string
