Rather than Debian shipping its own md5sum, why not just rely on the GNU
textutils md5sum(1) in coreutils or one of the not-yet-packaged md5(1)
utilities from *BSD, depending on whether or not one wants the '-' in
Historical precedence aside, it seems to me that third-party scripts
invoking md5sum will probably want the GNU behavior, and those invoking
md5 will want the BSD behavior.
The time for changing GNU md5sum's behavior has long passed.
