 These two families of functions return the value of C<x> after rotating
 all the bits by C<count> positions to the right (C<ecb_rotr>) or left
-(C<ecb_rotl>).
+(C<ecb_rotl>). There are no restrictions on the value C<count>, i.e. both
+zero and values equal or larger than the word width work correctly.
 
 Current GCC/clang versions understand these functions and usually compile
 them to "optimal" code (e.g. a single C<rol> or a combination of C<shld>
