I was not aware! That's embarrassing.

Now, I see

     If the hook variable is buffer-local, the buffer-local variable
     will be used instead of the global variable.  However, if the
     buffer-local variable contains the element ‘t’, the global hook
     variable will be run as well.

IMHO, that detail might look good in 24.1 Hooks section itself, as it
appears to be important. But maybe it is just me who did not notice
this.

In any case, there is no bug in what I reported. Just my
misunderstanding. Feel free to close.
