Horizontal collision of left and right spanner texts

[Rutger Hofman]

Hello list,

\version "2.18" .. "2.19.39"

I would like the left and right bound-detail texts of a TextSpanner to 
keep apart. Right now, they overlap horizontally in a fearful way. What 
can I do to keep them apart?

\score {
    \new Staff {
        \override TextSpanner.bound-details.left.text = 
\markup{\bold{wieder zurück ins}}
        \override TextSpanner.bound-details.right.text = 
\markup{\bold{Hauptzeitmaß}}
        c''1\startTextSpan |
        c''1\stopTextSpan
    }
}

Thanks,
