https://golang.org/pkg/flag/#PrintDefaults says

PrintDefaults prints, to standard error unless configured otherwise, ...

I couldn't see anywhere how to send its output anywhere else.

I dug through the source code and eventually made my way to (*FlagSet).SetOutput, but that was not at all obvious.

Also, it'd be nice if one could print the output to an io.Writer without having to mess with the global configuration. I couldn't see how to do that either.
