cmd/go, testing: remove redundant "for pkg" in coverage message
This is a transcript before this change. I've capitalized the text being removed.
Note that it is always near another line that already says fmt, marked with <<<
$ cd $GOROOT/src/pkg/fmt
$ go test -cover
PASS
coverage FOR FMT: 91.3% of statements
ok fmt 0.040s <<<
$ go test -coverpkg strconv
PASS
coverage FOR FMT: 64.9% of statements in strconv
ok fmt 0.039s <<<
$ go test -cover -c
$ ./fmt.test -test.covermode=set <<<
PASS
coverage FOR FMT: 91.3% of statements
$ go test -coverpkg strconv -c
$ ./fmt.test -test.covermode=set <<<
PASS
coverage FOR FMT: 64.9% of statements in strconv
That the summary printed by 'go test [options] fmt' is unchanged:
$ go test -cover fmt
ok fmt 0.040s coverage: 91.3% of statements
$ go test -coverpkg strconv fmt
ok fmt 0.038s coverage: 64.9% of statements in strconv
