perf list: Avoid confusion of perf output and the next command prompt
Distinguish the output of 'perf list --list-opts' or 'perf --list-cmds' with the next command prompt, which also happens in other cases (e.g. record, report ...). Example: Before this patch: $perf list --list-opts --raw-dump $ <-- the output and the next command prompt are at the same line After this patch: $perf list --list-opts --raw-dump $ <-- the new line Signed-off-by: Yunlong Song <yunlong.song@huawei.com> Cc: Paul Mackerras <paulus@samba.org> Cc: Peter Zijlstra <a.p.zijlstra@chello.nl> Cc: Wang Nan <wangnan0@huawei.com> Link: http://lkml.kernel.org/r/1425032491-20224-6-git-send-email-yunlong.song@huawei.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
