right bearing of meter signs

[Werner LEMBERG]

A quite serious problem with LilyPond in situations where the
available horizontal space is quite small: The right bearing of meter
signs appears to be fixed and thus much too big (see attached image).
IMHO, it should become smaller in such situations.  Looking into the
feta-nummer fonts I see that the glyphs already have zero right
bearing.  So my question is how can I control this?  Ideally, LilyPond
should do this automatically...
