[Rd] man page of hist points to truehist, which can't be viewed without loading a library?

I apologize for not being clear.  It actually does what you describe
in the underlying markup for the help page for "hist".  What I'm
referring to is the display of text, not in the source code which
generates the man page.  i.e.  it would be nice if the markup


generated text such as for example, "relatedFunction (in OtherPackage)".

So to be a bit more explicit, I was wondering whether:



   \code{\link[OtherPackage]{relatedFunction}}  (in OtherPackage)

would be better, stylistically.  I am leaning towards the use of the
latter.  I guess I could submit a patch for the former, not sure if I
can get it done for 2.0 (or if it is even too late).
