This does not complicate writing scripts.  It makes writing scripts easier,
because it makes "ln -s" predictable.

What a horrible idea.  "ln -s foo bar" is very simple now: it makes a
symlink at bar containing foo.  This is what you want in scripts. 

The correct way to do what you want is to write a *separate* program to
compute relative paths, e.g., 

    findrel B C

which would return a relative path to C starting from B, and then do this
in your script:

    ln -s `findrel B C` B/whatever
