Possible to write code to do this? Yes, of course, but probably not
desirable, see below.
Possible to set an option to cause this? No, not currently, and probably
never.
Importantly, a Cygwin symlink contains a *POSIX* path. The fact that the
symlink is also a windows shortcut is essentially just decoration.
Obviously, a normal shortcut does not contain a POSIX path. It would
probably be possible to deduce one, but there are good reasons for not doing
so: Extra data (icon, etc.) would be removed when shortcuts were saved and
restored with tar, for example.
