Can you use a boolean argument for that instead of namei flags?

How about:

.Fn llink
is kthe same as
.Fn link
except in the case where
.Fa name1
is a symbolic link.
In this case
.Fn llink
creates an additional (hard) link to the symbolic link, whereas
.Fn link
creates an additional (hard) link to the symbolic link's target.

but the patch may as well be good. :-) ]
