Comment #55 on issue 3330 by address@hidden: bracketify-stencil moves grob's  
refpoint
http://code.google.com/p/lilypond/issues/detail?id=3330

Regarding #54: analysis is _totally_ wrong.  The situation is much less  
sane than that.  \markup (as it is used here) is wrapped in an implicit  
\line, yes.  But actually,
\line { \bold \large\larger\larger { \hspace #-3.0 Lieblich, etwas  
geschwind } }
gets expanded into
\line { \bold \large\larger\larger \hspace #-3.0
        \bold \large\larger\larger Lieblich,
        \bold \large\larger\larger etwas
        \bold \large\larger\larger geschwind
}

Now good old \hspace previously _compensated_ for the current setting of  
word-space, backing it off.  The compensation is for a \large\larger\larger  
value of word-space, yet when the line gets assembled, it gets assembled  
with the standard word-space.  As a corollary, constructs of this kind are  
generally spaced all wrong since the spacing is not affected by the font  
size change.

Fabulous.  The actual difference in the images is indeed small, pretty much  
sub-pixel or so.  So the net effect of \hspace #-3 seems to survive well  
enough, with the visual difference being accountable just by \hspace #-3  
now no longer overcompensating for a word-space it considers larger than it  
actually is.

Morale?  We should probably have written something like
\bold\large\larger\larger \line { \hspace #-3 Lieblich, etwas geschwind }
in the first place in order to get the right interword space.
