Commit Message

grep: shortcut exit path for -q (#710)

* grep: shortcut exit path for -q

* -q flag of grep is concerned if a match was found in any file
* The program can terminate after the first match without searching in subsequent files
* GNU grep behaves in this way; strace on my Linux system confirms that only the 1st file in argument list is opened when that file contains a match

%strace  grep -q perl ar awk 2> trace # gnu grep
%grep open trace
...
openat(AT_FDCWD, "ar", _RDONLY|O_NOCTTY|O_LARGEFILE) = 3
^^^ final openat() in process

* avoid printing $Mult flag as part of string for grep -c
