please crossreferen basename and dirname manpage and add realpath ref

[Tomas Pospisek]

Since this is the 3rd time I was looking for tools that would return
me parts of and manipulate a path, and each time I would not remember
the exact names of the tools and I'd search for a while I'm submitting a
patch to crossreference the ones that I thought of. Hope you can include
them. Thanks!
