The following commit has been merged in the experimental branch:
commit 39261cd8d992322ce8ad77ee76a63a683cca21b2
Author: Måns Rullgård <mans at mansr.com>
Date:   Sun Feb 21 23:28:24 2010 +0000

    get/show_bits() can read up to MIN_CACHE_BITS bits
    
    The limit for get/show_bits_long() to use get/show_bits() directly
    should be MIN_CACHE_BITS, not 17.
