[1] we usually talk about connection profiles or devices/interfaces
[2] it would be better to say, if no suitable profile is ready to
autoconnect.
[3] `nm-online -s` waits until NetworkManager declares "startup
complete" reached.
I find the wording of the comment not very clear or useful.
Possibly I don't understand it properly, but that is a problem
for a comment that is supposed to help.
Remove it.
