Oh, right. Sorry, I forgot those discussions when I made those doc changes. I 
installed the attached to revert most of them, and to change the code to do a 
right thing with user-defined hash functions that return bignums. The revised 
documentation is now slightly vague about what Emacs does with hash codes when 
using them as indexes: it now says it "can reduce them" rather than it "reduces 
them" modulo the length of the array. The changes to the code are in 
hashfn_user_defined (which now reduces bignums to fixnums) and in exec_byte_code 
(which no longer attempts to optimize hash tests other than eq).
