Why is that a bug? If mzscheme is started via a soft link, the result
of `(find-system-path 'exec-file)' should be the soft link.

And it's ok for `(find-system-path 'collects-dir)' to return a result
relative to the binary.

The results of `(find-system-path 'exec-file)' and `(find-system-path
'collects-dir)' should be combined using `find-executable-path', which
follows soft links appropriately.
