I agree that this assumption is quite controversial even for myself --
it depends on what this function is used for. Adding an option may be
the best way to resolve it.

For example, one may manage the home directory configuration with one
type of VC. For configuration files for some applications, she may
rarely use them, so she simply cloned/checked out someone else's
configuration using a different VC, and symlink the file in the home dir
to the actual configuration file.
Another example: one may have a repository that contains files linking
to non-tracked files -- create a repository that link to common
configuration files such as the ones in /etc for easier management.
