I will, but my time is short.

Good question. At one time, they were much faster for some builds. I think
they are still faster if all you have is md5-mmx.S (i.e. 32 bit early asm).
However, the MD5 format since it now has intrinsic md5 is faster for most
builds.

They are NOT defined. However, the code within the -subformat:LIST function
was broken. It was walking an int, printing it out. So if things were
properly sequential, this int, and the format name 'lined' up. On the BE
builds, it was listing this:
dynamic_27 dynamic_29: Unicode(md5($s))
which within the new test suite, was causing it to think dynamic_27 was a
valid format on the BE systems, and also NOT making dynamic_29 a valid
format on the same build.
I have put a patch on the wiki. It is based on jumbo-4, but I am 99% sure it
will be just fine, applied to jumbo-5.
Jim.
