Comment #54 on issue 3330 by address@hidden: bracketify-stencil moves grob's  
refpoint
http://code.google.com/p/lilypond/issues/detail?id=3330

Regarding the "Lieblich, etwas geschwind": this appears due to hspace #-3  
now hiding the left extent.  In particular, the file
\markup
\column { x
	  \line { \bold \large\larger\larger { \hspace #-3.0 Lieblich, etwas  
geschwind } }
          y
}
\markup
\left-column { x
	  \line { \bold \large\larger\larger { \hspace #-3.0 Lieblich, etwas  
geschwind } }
          y
}

in current master displays the first column with "Lieblich..." shifted  
leftwards, while in the second column, the leftward shift is cancelled by  
\left-column again.

In contrast, with issue3330 applied, _both_ columns show the same leftward  
shift because the excess left-poking width is hidden.  The rationale for  
hiding the left extent is to avoid different results for
\line { \line { x \hspace #-3 } y } and \line { x \line { \hspace #-3 y } }
If the left extent of y caused by \hspace #-3 is not hidden, the  
equivalence would be broken.

So I am fine with this better being done via \translate rather than  
negative \hspace.
