If we later add another value to the possible ones, like for example
"auto", we might not want old versions of Git to fail with a "BUG:..."
message when they read config files tweaked for newer Git versions, so
I don't think we should die() here.
A warning would be ok, but given that in tweak_untracked_cache() we
decided to do nothing, I am thinking that it would be more consistent
to just do nothing here too.
