Fix an inaccuracy in the log command docs (#1844)

The "cli" package automatically generates the (default: x) message for the
flag type.
Current implementation leads to --follow option documentation
stuttering by `(default: true) (default: false)`. This is doubly wrong
because the option is off by default and first message can lead to
some sort of misunderstanding.
