I would prefer to print usage information in all such cases. This is more
informative and saves typing --help. It's the output of usage() that
should be fixed if people don't understand how to use the program.
I think we cannot afford context help, like "you didn't specify the
destination", "you should specify exactly one argument after -s" and so
on. This is error prone, rarely helpful and sometimes even misleading.
If I didn't specify the destination, why do you think I specified the
target? It's more likely to be a typo than my clear desire not to specify
an argument.
