h function in grep. c

[juhishake]

function 'o' in grep.c is not implemented like the other functions are. Programmer has to introduce the grepo flag and turn it to 1 if -o is detected. if yes then further the function o is called from functions.c

SOLUTION:
case o:
grepo = 1;
break;

if(grepo == 1){
o(fp, word);
grepo = 0;
}
