Comment 18 for bug 1713348

I try to protect e.g. reserve depending header packages from being purged and it works fine with usual kernel; if I want to keep linux-headers-4.4.0-92-generic, I should keep linux-headers-4.4.0-92 even if I am going to purge linux-headers-4.4.0-92-lowlatency (i.e. respective header package with different flavor). Maybe I can not rely on package naming generally; I hope there is some naming convention I can rely on. Anyway, I pushed some changes that aim to make the script work better with your development kernels and also work better with mawk as awk alternative, and display checklist better in debug mode.
