DynamicLineSpanner padding

[Orm Finnendahl]

Hi,

I observed a nasty behaviour trying to set the #'padding property of
the DynamicLineSpanner: The \p and \pp are not baseline-aligned with
the \ff or \mf.

Has this been reported before? To me this looks like something which
should rather get corrected in lilypond itself than cluttering the
script with different padding values before and after each \pp.
