I think it's intended as the former, though I'm quite surpised we have
been claiming for the last 20+ years that the space is deprecated.
Solaris "Linkers and Libraries" only mentions space as a separator.

PS: Don't have time to RTFS right now, the "or" in "space or colon" is
kinda misleading.  Is "a b:c" a list of (a, b, c), ("a b", "c") or
("a" "b:c")?
