If I understood your intention and patch correctly, cut should already
do what you need:

  ~$ perl -e 'print "A" x 800, "\n";' | cut -c -50
  AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA
  ~$ perl -e 'print "A" x 8, "\n";' | cut -c -50 | cat --show-ends
  AAAAAAAA$

Check out ``(coreutils)cut invocation''.
