    exactly what i smashed into my Makefile when i wrote md5:
        http://www.planete.net/~boyd/code/md5.bundle
    use the whole checksum.  all those bits are there for a _reason_.

I do use the whole checksum in wrap (I just don't 
believe in putting the whole things on web
pages for poor humans to stare at).  The problem
was that I moved some code around in wrap/create and
in one case the sum wasn't getting computed at all,
so you got whatever was on the stack, hence the
regularity.  The MD5 code was from a library that
has been correct for a good long time.

oh dear, time to 'do a boyd' [thanks rob].

i don't know what the problem was with the md5 checksums, but
RFC1321 says:

    A.5 Test suite

       The MD5 test suite (driver option "-x") should print the following
       results:

    MD5 test suite:
    MD5 ("") = d41d8cd98f00b204e9800998ecf8427e
    MD5 ("a") = 0cc175b9c0f1b6a831c399e269772661
    MD5 ("abc") = 900150983cd24fb0d6963f7d28e17f72
    MD5 ("message digest") = f96b697d7cb7938d525a2f31aaf161d0
    MD5 ("abcdefghijklmnopqrstuvwxyz") = c3fcd3d76192e4007dfb496cca67e13b
    MD5 ("ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789") =
    d174ab98d277d9f5a5611c2c9f419d9f
    MD5 ("123456789012345678901234567890123456789012345678901234567890123456
    78901234567890") = 57edf4a22be3c955ac49da2e2107b67a

that's scarey.  look at the high bits and the low bits the of checksums.
