Nothing printed with Huawei Honor8

I tried running like this:

adb logcat -v brief | pidcat -w50 -ld

This command works for me for all other devices, but not for Huawei Honor8. Logging in Android studio works for this device.

Here is an example log of adb logcat -v brief from that device:

$ adb logcat -v brief
int logctl_get(): open '/dev/hwlog_switch' fail -1, 13. Permission denied

Note: log switch off, only log_main and log_events will have logs!

I have excatly the same issue, on Mate9 Pro. And thanks to @teslacoil 's good catch. That’s the right point. I have forked the project and added one argument so that we can disable the break on empty line feature if we needed. Let me know if I need to create a PR to this repo.
