Wideining one measure so that dynamics don't overlap

[Reinhold Kainhofer]

I have a score with a whole note with \p on the first beat and \f on the third 
beat of the measure. I'm doing this using parallel music expressions:
  << { g1} { s2\p s\f} >> | % 42

Now, the problem is that the score consists almost entirely of whole or half 
notes, so that measure is too small and the f is printed above the p (since it 
would collide with the f). 

How can I make that one measure wider, while all other measures are spaced 
normally? I can't make the whole horizontal spacing wider, because then the 
music wouldn't fit on one page any more. However, there are several measures 
with whole notes, which can be a bit smaller to obtain the space needed for 
those wider measures.

Attached is a sample file for my case, where everything should fit in one line..

Cheers,
Reinhold
