grep: fix -x -v with certain pattern orders
We found out that busybox -x -v is a bit broken: ari@ari-thinkpad:~/busybox$ echo ' aa bb cc' | ./busybox grep -x -e 'aa.*' -e '.*bb.*' aa bb cc ari@ari-thinkpad:~/busybox$ echo ' aa bb cc' | ./busybox grep -x -v -e 'aa.*' -e '.*bb.*' ari@ari-thinkpad:~/busybox$ echo ' aa bb cc' | ./busybox grep -x -e '.*aa.*' -e 'bb.*' aa bb cc ari@ari-thinkpad:~/busybox$ echo ' aa bb cc' | ./busybox grep -x -v -e '.*aa.*' -e 'bb.*' aa bb cc Last one is wrong. This patch fixes the issue by making sure that the variable 'found' never makes a transition from 1 to 0, as this would mean that grep previously found a match on this input line.
