The funny thing is; that sentence continues (on a new line) like:

"friends are traced and the pointers, together with additional"

So while it then has cross-references to a few functions, all 'friends'
are left dangling. So what's the point of the cross-references?

Also, 'make ctags' and follow tag (ctrl-] for fellow vim users) will get
you to the function, no magic markup required.

That would be good; less markup is more.
