Note/clef collision due to translated TextScript markup

[Nicolas Sceaux]

Hi,

In the following example, the clef collides with the previous note,
because of the translated markup.

\version "2.11.50"
<<
 \new Staff {
   \clef treble a'8 g' s4
   \clef alto r8^\markup { \null \translate #'(-4 . 0)
                           \typewriter "\\null \\translate #'(-4 . 0)  
text" }
   c''8 a'4
 }
 \new Staff { \clef bass s4 g c f }
>>
