info/navigate: Correct and clarify

Don't claim the lowest-numbered land unit is always the leader.

Reword the explanation of the prompt.

Update example output for current code.

Clarify that a destination sector is also accepted interactively, not
just on the command line.

Missiles interdict just the valuable ships, unlike other interdiction.
