On my system I get with:
print *, "--------------------------------------"
print "(F0.0)", -0.0   ! => -0.
print "(F3.0)", -0.0   ! => -0.
print "(F2.0)", -0.0   ! => **
print "(F1.0)", -0.0   ! => *
print *, "--------------------------------------"
print "(F0.1)", -0.0   ! => -.0
print "(F3.1)", -0.0   ! => -.0
print "(F2.1)", -0.0   ! => **
print "(F1.1)", -0.0   ! => *

This. The difference being my signature zero.
 --------------------------------------
-0.
-0.
**
0
 --------------------------------------
-.0
-.0
**
0

I confess, it does not look consistent. Next time slice, I will update it.  ;)
