[Colin Guthrie]

'Twas brillig, and David Herrmann at 30/08/13 14:50 did gyre and gimble:
> +        subsystem = subsystem ? : "";
> +

zomg!!11eleven! This makes perfect sense but somehow this is the first
time I've seen this syntax before where the value between ? and : is
inherited from the test itself... nice!

For what it's worth the two other uses of this syntax in the systemd
codebase don't have a space between the ? and : (dunno if this qualifies
for a coding standard tho'!)

/me will now go and craw back under his rock...
