Actually, I found another bug which is even more interesting: #564034.
There, the netcat-openbsd maintainer (cc:ed) announced that he had
restored the original behavior if -q is not given:

--8<---------------cut here---------------start------------->8---
netcat-openbsd (1.89-4) unstable; urgency=low

  * Quit immediately after EOF if -q is not given (i.e. make the default
    equivalent to -q 0). This is the standard upstream behavior and what
    other Linux distributions use. It is different from netcat-traditional,
    but compatibility with other versions of OpenBSD netcat is more
    important. (Closes: #502188)

--8<---------------cut here---------------end--------------->8---

So, am I right that we do not need anymore the -q patch if libvirt-bin
and virt-manager depends on netcat-openbsd >= 1.89-4?

Thx, bye,
Gismo / Luca
