Reading the --help text of 'seq' (5.1.3 from alpha) I'm inclined to
assume
seq 3 1
and
seq 3 -1 1
should result in the same output:
3
2
1
But 'seq 3 1' does not produce any output. The --help text:
INCREMENT is usually negative if FIRST is greater than LAST.
Maybe, current behavior is covered by the meaning of "usually" (I'm not
a native speaker, you know).
You may also nuke this surious space at the end of the line:
