I mis-spoke, sorry, what md5check does is what i'll call a quick
check via metaflac --show-md5sum and then compares that to a
previously stored ffp text file

then it also calls flac -t which i'll call the extended check

where i mis-spoke is it does not use md5sum --check (because that
doesn't work on ffp files)

the quick check succeeds if the file has been truncated after the
ffp.txt has been generated (when the file was still good) because
the internal md5sum must be stored at the beginning of the file
and is still retrieved ok by --show-md5sum

so i was thinking that
if it were stored at beg and end that would fix that but any other
corruption could happen anywhere in middle and it would still be
an issue - so using --test every time to make sure is the best way
to go
