Try a combination of:

vc-follow-symlinks's value is t

Documentation:
*What to do if visiting a symbolic link to a file under version control.
Editing such a file through the link bypasses the version control system,
which is dangerous and probably not what you want.

And:

(setq
 backup-by-copying t      ; don't clobber symlinks
 version-control t)       ; use versioned backups
