Is there a standard function that does something akin to an inverse of
'merge-pathnames'? I need to find a pathname of one directory relative
to another:

(split-pathnames "/home/user/projects/my-project"
                 "projects/my-project")
  => "/home/user"

I can't seem to find a portable way to do this.

Have you looked at ENOUGH-NAMESTRING?
