An introductory word: linecut was specifically designed with solely
one purpose in mind.
Feature comparison (should I be wrong, correct me):
Compared to sed:
- sed doesn't easily allow for aligned line-numbering output.
Compared to head:
- head always works from the beginning whereas linecut doesn't.
Compared to tail:
- tail always works towards the end whereas linecut doesn't.
Sure, you could chain 'head | tail' (or vice versa), build a wrapper
script in awk/perl or some other script language around (s)ed or cut,
but I didn't like the idea.

Good catch.
