4.15-stable review patch. If anyone has any objections, please let me know.
------------------ From: Adam Borowski <kilob...@angband.pl> commit 3a129cc2151425e5aeb69aeb25fbc994ec738137 upstream. Like %pK already does, print "00000000" instead. This confused people -- the convention is that "(null)" means you tried to dereference a null pointer as opposed to printing the address.
