Stem extension troubles...

[Chakat Sandwalker]

I'm not sure if this might have been in the archives, but this isn't 
exactly something easy to find information or how-tos on.

I'm trying to typeset a ragtime piece I finished writing a couple of 
days ago, and I've found that I've run into a headache.  I have a bar in 
which I had a tie into a note/rest chord combination.  I accidentally 
found out that a tie can't be linked to notes inside a << \\ >> context, 
so I had to figure out a workaround.  I found one, but I now have the 
problem of a beam passing through a bass clef, as demonstrated in the 
following code snippet:

\layout{ragged-right=##t}
\relative c'' { \clef treble g8 c16 g~ g8 \clef bass <g,,, g'> }

This isn't my preferred way of doing it, but it seems the easiest.  
However, it looks bad to have the beam between the notes passing through 
the clef sign.  Is it possible to extend the stems of the quavers so 
that the beam passes /above/ the clef sign?  This problem has been 
driving me to distraction all day.  I'm don't really understand more 
than the basics of Lilypond -- the more complicated code involving 
overrides and contexts is over my head, unfortunately, and what extra 
code I have used was pretty  much copy-and-pasted from the example code 
given in the main documentation.

If anyone could help me with this, it would be very much appreciated.
