No, it is the only test made before calling this function (indeed, the
function doesn't make any such test). My patch doesn't affect this: the
only test performed before calling this function is still the
modtime test.
It's important to know where the test is performed because:
This function is called automatically by Emacs on the proper
occasions. It exists so you can customize Emacs by redefining it.
See the file @file{userlock.el} for the standard definition.
So if you want to "update the doc" here, we'd have to actually state
what the standard definition does (we currently don't do actually that).
