Title: Fix error help message.

Before:

```
$ ./doozer set
set: wrong number of arguments
Use: %!s(func()=0x402f19) [options] set [options]

Sets the body of the file at .

The body is read from stdin. If is not greater than or equal to
the revision of the file, no change will be made.

Prints the new revision on stdout, or an error message on stderr.
```

Sets the body of the file at .

The body is read from stdin. If is not greater than or equal to
