Cleanup pkg-rquery.8
- Use Ns (non-breaking space) instead of Sm (switching space mode)
- Remove long options from SYNOPSIS, describing them in DESCRIPTION
should be just enough
- Remove Ao/Ac (angle brackets); I understand that vt doesn't seem
to display underlines correctly, but it should be "fixed" in mandoc
instead to change the Ar output style if anywhere
- Use Ds (non-existent and standard for such cases) width specifier
everywhere except for single character heads
- Fix other issues reported by mandoc's lint
