rc man/doc: Don't show groff warnings

Browse Source 
Sometimes the implementation of `man` will display errors, e.g.

```
<standard input>:4808: warning [p 54, 13.2i]: can't break line
```

Those errors are harmless but are still reported on the debug buffer,
so we hide them by redirecting the standard error stream to /dev/null.
