Yes, I think the comment should just go.  Nobody used that alphabet
form since it was written in d17cf5f3 (tests: Introduce test_seq,
2012-08-04).

Neither am I, but I think it is prudent to drop that "letters".  The
comment even says the letter form is not portable already, so the
mention of GNU seq(1) is not helping at all.
