Hi,

I like this idea. Just in case Debian grows to a million packages.
But i understand that i would need two separate files for sorting.

  grep ' ./pool/' <merged_md5sum.txt | uniq >file1
  fgrep -v ' ./pool/' <merged_md5sum.txt | polish_md5sum_txt >file2
  sort -k 2 -m file1 file2 >temp_file

More temporary files means more need for pre-existence tests and more
cleanup effort.
Currently i just have to concatenate two stdout streams.

Seems to be the best decision for now.
(Unless some shell wizzard shows a way to pipe both streams separately
into sort -m while staying dash compatible and without the need for new
persistent file objects which have to be cleaned up afterwards.)

Actually we did not yet identify a use case where md5sum.txt needs to
be sorted at all. I only sort it because the input files are sorted.
