svnversion doesn't have a --help option.

What you are seeing are error messages generated when command line
parsing fails and so stderr is probably the correct stream.

If you want to change the behaviour it's probably be better to make
the error messages shorter, by 1) removing the usage message when
invalid options are supplied and 2) making a bare 'svnversion' suggest
adding '--help'. Then add a --help option that prints the usage to
stdout.
