GIT version: values writing

[Hans Aberg]

There seems to be a bug in GIT version when writing the 'values' data  
type.
  (list 2 (values 3 4) 5)
  $1 = (2 3 5)
with the value 4 lost In guile-1.8.8, it would write
  (2 #<values 3 4> 5)
The top level write out all values:
  (values 3 4)
  $2 = 3
  $3 = 4

The values correspond to tuples, so they might be written out as  
ordinary tuples, though that is perhaps not Scheme style.
