The reason why hash one is broken is the "workaround" introduced into
version 1.5.
$body_copy =~ s/[[:graph:]]+//go;
This can not work.
Hash one is supposed to do this: Condense all consecutive, identical
whitespace chars into a single occurrence, then drop the graph chars and
compute the md5sum for the remaining whitespace signature.
The "workaround" above removes words *first*, usually resulting in a
bunch of spaces per line. With the original algorithm, these are exactly
what's being hashed! With the "workaround", they falsely get condensed
into a single space per line once the original hash generation is being
run.
