evil-snipe-override-evil in doc but not in code

[st--]

What would you like to know?

The docstring of evil-snipe-repeat-keys says:

evil-snipe/evil-snipe.el

Line 119 in c07788c

If `evil-snipe-override-evil' is non-nil, this applies to f/F/t/T as well."

but there is no occurrence of evil-snipe-override-evil anywhere in the code, so how would it be able to work?
