Comment(by nicklas):

 It looks like this behavior is intended from the comment in the end of
 lwgeom_functions_basic.c:
         /* Mirror non-collections right back */

 But I agree that this is no good.

 As the documentation is written now, it should definitly give an error
 message if the inputed geometry is not a collection, but it would also
 make sense as in the testcase.patch, the inputed geometry is mirrored if
 and only if it is of the type that is asked for. But then that should be
 reflected in the documentation to.

 I can do the changes if someone decides which way to go
